Human Body Essay

Introduction.

It is surprising to see how a human body functions with maximum capability. Whether we are talking, walking or seeing, there are distinct parts in our body that are destined to perform a particular function. The importance of each part is discussed in this human body essay. When we feel tired, we often take a rest and lie down for a moment. But our body continues to work, even when we take a break. Even if you are tired, your heart will not stop beating. It pumps blood and transports nutrients to your body.

The human body is made up of many parts and organs that work together to sustain life in our body. No organ or body part is more important than the other, and if you ignore one of them, then the whole body will be in pain. So, let us teach the significance of different parts of the body to our children through this essay on human body parts in English. To explore other exciting content for kids learning , head to our website.

Different Systems in the Human Body

The human body looks very simple from the outside with hands, legs, face, eyes, ears and so on. But, there is a more complex and significant structure inside the body that helps us to live. The human body is made up of many small structures like cells, tissues, organs and systems. It is covered by the skin, beneath which you could find muscles, veins, and blood. This structure is formed on the base of a skeleton, which consists of many bones. All these are arranged in a specific way to help the body function effectively. In this human body essay, we will see the different systems in the human body and their functions.

The circulatory system, respiratory system, digestive system and nervous system are the main systems of the human body. Each system has different organs, and they function together to accomplish several tasks. The circulatory system consists of organs like the heart, blood and blood vessels, and its main function is to pump blood from the heart to the lungs and carry oxygen to different parts of the body.

Next, we will understand the importance of the respiratory system through this human body essay in English. The respiratory system enables us to breathe easily, and it includes organs like the lungs, airways, windpipe, nose and mouth. While the digestive system helps in breaking down the food we eat and gives the energy to work with the help of organs like the mouth, food pipe, stomach, intestines, pancreas, liver, and anus, the nervous system controls our actions, thoughts and movements. It mainly consists of organs like the brain, spinal cord and nerves.

All these systems are necessary for the proper functioning of the human body, which is discussed in this essay on human body parts in English. By inculcating good eating habits, maintaining proper hygiene and doing regular exercises, we can look after our bodies. You can refer to more essays for kids on our website.

Frequently Asked Questions on Human Body Essay

The human body is a complex and fascinating entity that is the epitome of biological engineering. It is a marvel of evolution, honed over millions of years to become a highly efficient machine capable of extraordinary feats. This essay delves into the intricacies of the human body, exploring its structure, function, and the symbiotic relationship between its various systems.

Structural Complexity

The human body is composed of several levels of structural organization. At the most basic level, we find cells – the building blocks of life. These cells group together to form tissues, which in turn combine to form organs. The organs then work together in organ systems to perform specific functions. The human body comprises eleven organ systems, each with its own unique role, yet they all work in unison to maintain homeostasis.

Functional Dynamics

The functionality of the human body is a testament to the intricate design and coordination of its systems. The circulatory system, for instance, is responsible for the transportation of nutrients, oxygen, and waste products around the body. The nervous system, on the other hand, acts as the body’s control center, sending and receiving signals to and from different parts of the body. The respiratory system facilitates the exchange of gases, while the digestive system breaks down food into nutrients that the body can use. These systems, among others, work in a coordinated fashion to ensure the smooth functioning of the body.

The Symbiotic Relationship

The relationship between the various systems of the human body is symbiotic in nature. Each system relies on the others to function optimally. For instance, the respiratory and circulatory systems work together to deliver oxygen to cells and remove carbon dioxide. The nervous system controls the rate of breathing and heart rate based on the body’s needs. The endocrine system, with its hormones, influences almost every other system, affecting growth, metabolism, mood, and more. This interdependence underscores the complexity and efficiency of the human body.

Adaptability and Resilience

One of the most remarkable characteristics of the human body is its adaptability and resilience. It can adapt to various environmental conditions, from the freezing temperatures of the Arctic to the scorching heat of the desert. The immune system, a complex network of cells, tissues, and organs, defends the body against harmful microorganisms, demonstrating the body’s resilience. Furthermore, the body has remarkable healing capabilities, with systems in place to repair damage and restore function.

In conclusion, the human body is an intricately designed system that showcases the marvels of evolution. Its structural complexity, functional dynamics, symbiotic relationship between systems, and adaptability and resilience are awe-inspiring. Understanding the human body not only allows us to appreciate the marvel that it is but also equips us with the knowledge to take better care of it. Indeed, the human body is a testament to the sophistication and beauty of biological engineering.

What are the systems of the body? Fast facts about the human body and how it works

Learn all about the human body's many systems and some of its individual organs, both vital and vestigial.

The human body is a complex network of systems that work together to keep life-sustaining processes running smoothly. These systems break down food for fuel, clear away waste, repair damaged tissues and DNA, fight infectious germs and monitor the outside world so we can move through it safely. 

Many scientists spend their days working to understand how each bodily system performs its jobs, how the systems interact, and what can happen when one or more of them falter. Such malfunctions can stem from aging or disease, for instance, and through medical care, doctors aim to get derailed systems back on track. 

Here's a quick rundown of the systems of the human body, its vital organs and its "vestigial" organs, as well as a few fascinating facts about how the body works.

What are the different systems of the human body? 

Our bodies consist of a number of biological systems that carry out specific functions necessary for everyday living. Some organs and tissues play roles in multiple systems at once.

Related: Strange, two-faced brain cells confirmed to exist, and they may play a role in schizophrenia  

Circulatory : The job of the circulatory system is to move blood, nutrients, oxygen, carbon dioxide and hormones around the body. It consists of the heart, blood, blood vessels, arteries and veins. According to the Cleveland Clinic , the adult human body's network of blood vessels is more than 60,000 miles (around 100,000 kilometers) long. 

Digestive: The digestive system consists of a series of connected organs that together allow the body to break down and absorb nutrients from food and remove waste. It includes the mouth, esophagus, stomach, small intestine , large intestine, rectum and anus. The large intestine is home to microorganisms that are collectively called the gut microbiome and influence our health in various ways . The liver and pancreas also have roles in the digestive system because they produce digestive juices filled with enzymes to break down the components of food, such as carbohydrates , fats and proteins , according to the National Institute of Diabetes and Digestive and Kidney Diseases .

Endocrine: The endocrine system consists of a network of glands that secrete hormones — long-range chemical messengers that regulate how cells and tissue function — into the blood. These hormones, in turn, travel to different tissues and regulate many bodily functions, such as metabolism , growth and sexual function, according to Johns Hopkins Medicine . For example, the pancreas releases the hormones insulin and glucagon to regulate blood sugar . Conditions like diabetes and insulin resistance arise from the body having too little insulin or not responding to it adequately.

Immune: The immune system is the body's defense against bacteria , viruses and other pathogens that may be harmful. Components of the system include the lymph nodes , which contain infection-fighting cells called lymphocytes. These lymphocytes are one of many types of leukocyte , or white blood cell. The immune system also includes the spleen , the bone marrow and a gland called the thymus . The immune system can learn to recognize antigens — proteins on the surface of bacteria, fungi and viruses — and alert the body to their presence. Some immune cells make proteins called antibodies that attach to these antigens and mark invaders for destruction. 

Lymphatic: The lymphatic system includes the lymph nodes, lymph ducts and lymph vessels and is considered part of the immune system. Its main job is to make and move lymph , a clear fluid that contains white blood cells. The lymphatic system also removes excess lymph fluid from the body's tissues and returns it to the blood.

Nervous: The nervous system controls both voluntary actions, such as conscious movements, and involuntary actions,like breathing, and it sends signals to and detects signals from different parts of the body. Conscious actions are controlled by the somatic nervous system, while involuntary actions are controlled by the autonomic nervous system. The autonomic nervous system dictates whether we're in " rest and digest " or " fight or flight " mode. The nervous system can further be split up into the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system, or the nerves connecting the CNS to every other part of the body.

Muscular: The body's muscular system consists of hundreds of muscles that aid movement, blood flow and other bodily functions, according to the Library of Congress . There are three types of muscle: skeletal, which is connected to bone and helps with voluntary movement; smooth, which is found inside organs and helps to move substances through them; and cardiac, which is found in the heart. The body's largest muscle by mass is the gluteus maximus, but the two latissimus dorsi are the largest in terms of surface area.

Related: Why is it harder for some people to build muscle than others?

Reproductive: The reproductive system allows humans to produce offspring. The male reproductive system includes the penis and the testes , which produce sperm. The female reproductive system includes the vagina, uterus and ovaries, which produce eggs. During fertilization, a sperm cell will fuse with an egg cell that, in a successful pregnancy, will then implant in the uterus. The fertilized egg will then mature into what's called a blastocyst, then an embryo and, finally, a fetus. A placenta forms to support this process. 

Skeletal: Our bodies are supported by the skeletal system , which contains between 206 and 213 bones in an adult human body, due to slight variations in people's anatomy, according to the medical resource StatPearls . These bones are connected by tissues called tendons, ligaments and cartilage. As infants, humans have about 300 bones , but some fuse together as the child grows. The skeleton not only helps us move but is  also involved in the production of blood cells and the storage of calcium. The teeth are also part of the skeletal system, but they aren't considered bones . The smallest bones in the body are found in the ear, and the largest is the femur, or thigh bone, which is also one of the heaviest body parts .

Respiratory: The respiratory system allows us to take in oxygen and expel carbon dioxide through breathing. It includes the lungs ; trachea, or windpipe; and the diaphragm, a muscle that pulls air into and pushes air out of the lungs.

Urinary: The urinary system helps eliminate a waste product called urea, which is produced when certain foods are broken down. The system includes the two kidneys; two ureters, or tubes leaving the kidneys; the bladder; two sphincter muscles; and the urethra. The kidneys filter blood in the body to make urine that then travels down the ureters to the bladder and exits the body through the urethra.

Integumentary: The skin, hair and nails make up the integumentary system. Skin is the body's largest organ . It protects our innards from the outside world, serving as our first defense against bacteria, viruses and other pathogens, for instance. Our skin also helps regulate body temperature and eliminate waste through perspiration, or sweat.

What are the body's vital organs?

Click the purple circles to learn about the body's vital organs, including the brain, lungs, heart, liver and kidneys. They're considered vital because you need a functioning brain, heart, liver, at least one kidney and at least one lung to survive. That said, there are medical devices and treatments that can make up for a loss of function in these organs, at least temporarily — for example, ECMO machines can do the work of the heart and lungs, and dialysis can filter the blood of people with kidney failure.

• The average adult male body contains about 36 trillion cells , the average adult female body contains 28 trillion cells and a 10-year-old has about 17 trillion. 
• It's often said that there are 78 organs in the human body , but the number actually differs depending on whom you ask. 
• There's a popular idea that the body replaces itself every seven years . But that's not really true, because tissues renew themselves at different rates. 
• Oxygen is the most common element in the human body , followed by carbon. 
• The average adult body contains about 1.2 to 1.5 gallons (4.5 to 5.5 liters) of blood . 
• Humans' average body temperature has fallen slightly over time, so it's no longer 98.6 degrees Fahrenheit (37 degrees Celsius). 
• The most detailed map of the human brain to date contains more than 3,300 types of brain cells . 

What are vestigial organs?

There are arguably some parts of the human body that don't serve any useful purpose, such as the male nipple. That said, the usefulness of some organs is still up for debate , as scientists have often judged the worth of body parts before discovering their purposes. 

Broadly speaking, vestigial body parts are defined as those that have lost their original physiological significance to humans over the course of evolutionary history. The idea is that, while we inherited them from an ancient ancestor, we could really do without them in the modern day. 

— Scientists just discovered a new way cells control their genes — it's called 'backtracking'

— New part of the body found hiding in the lungs

— Scientists stumble upon a new part of a cell in one of the most studied animals on Earth  

Wisdom teeth are held up as one example of a vestigial body part, as the modern human jaw is often too small to accommodate a third set of molars. Some people also carry remnants of a vomeronasal organ that is largely thought to be nonfunctional in humans; animals use equivalent organs to detect each other's pheromones. 

Some scientists consider the human tailbone, or coccyx, vestigial because it's no longer a full-blown tail. But it's far from useless, as it still anchors many muscles, ligaments and tendons. And the appendix has gotten a bad rap for supposedly being both vestigial and useless, but more recently, scientists have uncovered possible functions for the long-maligned body part.

“Achy Breaky Heart”

Billy Ray Cyrus's song "Achy Breaky Heart" has lyrics suc as: Heartache, heartbreak...it all has to do with love. Did you ever wonder why the heart is associated with love? The heart was once thought to be the center of all thought processes, as well as the site of all emotions. This notion may have stemmed from very early anatomical dissections that found many nerves can be traced to the region of the heart. The fact that the heart may start racing when one is excited or otherwise emotionally aroused may have contributed to this idea as well. In fact, the heart is not the organ that controls thoughts or emotions. The organ that controls those functions is the brain. In this concept, you’ll be introduced to the heart, brain, and other major organs of the human body.

Human Organs

An organ is a collection of tissues joined in a structural unit to serve a common function. Organs exist in most multicellular organisms, including not only humans and other animals but also plants. In single-celled organisms such as bacteria, the functional equivalent of an organ is an organelle.

Tissues in Organs

Although organs consist of multiple tissue types, many organs are composed of the main tissue that is associated with the organ’s major function and other tissues that play supporting roles. The main tissue may be unique to that specific organ. For example, the main tissue of the heart is the cardiac muscle, which performs the heart’s major function of pumping blood and is found only in the heart. The heart also includes nervous and connective tissues that are required for it to perform its major function. For example, nervous tissues control the beating of the heart, and connective tissues make up heart valves that keep blood flowing in just one direction through the heart.

Vital Organs

The human body contains five organs that are considered vital for survival. They are the heart, brain, kidneys, liver, and lungs. The locations of these five organs and several other internal organs are shown in Figure \(\PageIndex{2}\). If any of the five vital organs stops functioning, the death of the organism is imminent without medical intervention.

• The heart is located in the center of the chest, and its function is to keep blood flowing through the body. Blood carries substances to cells that they need and also carries away wastes from cells.
• The brain is located in the head and functions as the body’s control center. It is the seat of all thoughts, memories, perceptions, and feelings.
• The two kidneys are located in the back of the abdomen on either side of the body. Their function is to filter blood and form urine, which is excreted from the body.
• The liver is located on the right side of the abdomen. It has many functions, including filtering blood, secreting bile that is needed for digestion, and producing proteins necessary for blood clotting.
• The two lungs are located on either side of the upper chest. Their main function is exchanging oxygen and carbon dioxide with the blood.

Human Organ Systems

Functionally related organs often cooperate to form whole organ systems. Figure \(\PageIndex{3}\) and Figure \(\PageIndex{4}\) show 11 human organ systems, including separate diagrams for the male and female reproductive systems. Some of the organs and functions of the organ systems are identified in the figure. Each system is also described in more detail in the text that follows. Most of these human organ systems are also the subject of separate chapters in this book.

Integumentary System

Organs of the integumentary system include the skin, hair, and nails. The skin is the largest organ in the body. It encloses and protects the body and is the site of many sensory receptors. The skin is the body’s first defense against pathogens, and it also helps regulate body temperature and eliminate wastes in sweat.

Skeletal System

The skeletal system consists of bones, joints, teeth. The bones of the skeletal system are connected by tendons, ligaments, and cartilage. Functions of the skeletal system include supporting the body and giving it shape. Along with the muscular system, the skeletal system enables the body to move. The bones of the skeletal system also protect internal organs, store calcium, and produce red and white blood cells.

Muscular System

The muscular system consists of three different types of muscles, including skeletal muscles, which are attached to bones by tendons and allow for voluntary movements of the body. Smooth muscle tissues control the involuntary movements of internal organs, such as the organs of the digestive system, allowing food to move through the system. Smooth muscles in blood vessels allow vasoconstriction and vasodilation and thereby help regulate body temperature. Cardiac muscle tissues control the involuntary beating of the heart, allowing it to pump blood through the blood vessels of the cardiovascular system.

Nervous System

The nervous system includes the brain and spinal cord, which make up the central nervous system, and nerves that run throughout the rest of the body, which make up the peripheral nervous system. The nervous system controls both voluntary and involuntary responses of the human organism and also detects and processes sensory information.

Endocrine System

The endocrine system is made up of glands that secrete hormones into the blood, which carries the hormones throughout the body. Endocrine hormones are chemical messengers that control many body functions, including metabolism, growth, and sexual development. The master gland of the endocrine system is the pituitary gland, which produces hormones that control other endocrine glands. Some of the other endocrine glands include the pancreas, thyroid gland, and adrenal glands.

Cardiovascular System

The cardiovascular system (also called the circulatory system) includes the heart, blood, and three types of blood vessels: arteries, veins, and capillaries. The heart pumps blood, which travels through the blood vessels. The main function of the cardiovascular system is transport. Oxygen from the lungs and nutrients from the digestive system are transported to cells throughout the body. Carbon dioxide and other waste materials are picked up from the cells and transported to organs such as the lungs and kidneys for elimination from the body. The cardiovascular system also equalizes body temperature and transports endocrine hormones to cells in the body where they are needed.

Urinary System

The urinary system includes the pair of kidneys, which filter excess water and a waste product called urea from the blood and form urine. Two tubes called ureters carry the urine from the kidneys to the urinary bladder, which stores the urine until it is excreted from the body through another tube named the urethra. The kidneys also produce an enzyme called renin and a variety of hormones. These substances help regulate blood pressure, the production of red blood cells, and the balance of calcium and phosphorus in the body.

Respiratory System

Organs and other structures of the respiratory system include the nasal passages, lungs, and a long tube called the trachea, which carries air between the nasal passages and lungs. The main function of the respiratory system is to deliver oxygen to the blood and remove carbon dioxide from the body. Gases are exchanged between the lungs and blood across the walls of capillaries lining tiny air sacs (alveoli) in the lungs.

Lymphatic System

The lymphatic system is sometimes considered to be part of the immune system. It consists of a network of lymph vessels and ducts that collect excess fluid (called lymph) from extracellular spaces in tissues and transport the fluid to the bloodstream. The lymphatic system also includes many small collections of tissue, called lymph nodes, and an organ called the spleen, both of which remove pathogens and cellular debris from the lymph or blood. In addition, the thymus gland in the lymphatic system produces some types of white blood cells (lymphocytes) that fight infections.

Digestive System

The digestive system consists of several main organs — including the mouth, esophagus, stomach, and small and large intestines — that form a long tube called the gastrointestinal (GI) tract. Food moves through this tract where it is digested, its nutrients absorbed, and its waste products excreted. The digestive system also includes accessory organs (such as the pancreas and liver) that produce enzymes and other substances needed for digestion but through which food does not actually pass.

Male and Female Reproductive Systems

The reproductive system is the only body system that differs substantially between individuals. There is a range of Biological sex, but most books divide them into male and female. We will discuss the Biology of sex in detail in the reproductive and development chapters.

Feature: Human Biology in the News

Organ transplantation has been performed by surgeons for more than six decades, and you’ve no doubt heard of people receiving heart, lung, and kidney transplants. However, you may have never heard of a penis transplant. The first U.S. penis transplant was performed in May of 2016 at Massachusetts General Hospital in Boston. The 15-hour procedure involved a team of more than 50 physicians, surgeons, and nurses. The patient was a 64-year-old man who had lost his penis to cancer in 2012. The surgical milestone involved grafting microscopic blood vessels and nerves of the donor organ to those of the recipient. As with most transplant patients, this patient will have to take immunosuppressing drugs for the rest of his life so his immune system will not reject the organ. The transplant team said that their success with this transplant “holds promise for patients with devastating genitourinary injuries and disease.” They also hope their experiences will be helpful for gender reassignment surgery.

Theseglands produce hormones that are responsible for regulating mood,sexual desires, the functioning of tissues, metabolism, andreproduction.

Therespiratory system is primarily responsible for gaseous exchange inthe body. That is, taking in of oxygen gas and taking out of carbondioxide that is done through the lungs. Therefore, the respiratorysystem is responsible for supplying oxygen to all parts of the bodyusing the red blood cells.

Theskeletal system is made up of all joints and bones in the body. Theskeletal system supports and protects soft tissues that are found inthe body. Also, the skeletal system allows joints to move byproviding points for muscles attachment. Furthermore, bones storecalcium, energy, which is in the form of fats, and iron among otherelements.

Thenervous system constitutes of neurons that send out signals betweendifferent body parts. The nervous system is usually divided into twoparts the central nervous system and the peripheral nervous system(Smith et al., n.d). The nervous system controls blood pressure,senses of touch, and breathing among others.

Theexcretory system is responsible for discharging wastes from the body.The excretory system eliminates wastes from the body so as to controlthe process of homeostasis as well as preventing body damage. Organsthat are involved in the excretion process are the liver, kidney,large intestines, and the skin.

Thereproductive system consists of organs found in either males orfemales, and these organs are responsible for procreation. Thereproductive system of a male is made up of testes and penis whilethe female reproductive consists of the vagina, uterus, and theovaries.

Themuscular system usually consists of skeletal, smooth, and cardiacmuscles. The muscular system is checked by the nervous system. Thus,muscular system is responsible for the body movements, bloodcirculation in the body, and maintenance of body posture.

Thedigestive system converts food into nutrients that are easilyabsorbed by the body while the rest is converted into energy. Thedigestive system consists of the alimentary canal that is made up ofthe large intestine, stomach, pharynx, esophagus, stomach, and oralcavity (Smith et al., n.d). In the digestive system, the followingactivities take place: mixing and movement of food, ingestion,secretion, digestion, and absorption.

Theimmune system protects the body from infections caused bymicro-organisms. The main role of the immune system is to keep peoplehealthy and free from diseases. When the immune system fails to workwell, people get infected and suffer from diseases.

Thecirculatory system consists of many networked organs and vessels thatare responsible for the flow of blood to and from cells. Also, thecirculatory system helps in the transportation of oxygen, nutrients,hormones, and gases in the body.
