List of Organs in the Human Body: Organs are recognizable structures of the body (for example, the heart, lungs, liver, eyes, and stomach) that perform specific functions. An organ is made up of many types of tissues and therefore many types of cells. In biology, an organ (from the Latin “organum” meaning a tool or apparatus) is a collection of tissues that structurally form a functional unit specifically to perform a particular function. And your heart, kidneys and lungs are examples of organs.
अंग शरीर की पहचानने योग्य संरचनाएं हैं (उदाहरण के लिए, हृदय, फेफड़े, यकृत, आंखें और पेट) जो विशिष्ट कार्य करते हैं। एक अंग कई प्रकार के ऊतकों और इसलिए कई प्रकार की कोशिकाओं से बना होता है। जीव विज्ञान में, एक अंग (लैटिन “ऑर्गनम” से जिसका अर्थ है एक उपकरण या उपकरण) ऊतकों का एक संग्रह है जो संरचनात्मक रूप से एक विशेष कार्य करने के लिए विशेष रूप से एक कार्यात्मक इकाई बनाता है। और आपका हृदय, गुर्दे और फेफड़े अंगों के उदाहरण हैं।
What is an organ?
An organ is composed of a single type of tissue, which is well-organized to perform specific functions in all living things, including plants, animals, birds, insects, reptiles, mammals, and humans.
Organs collectively make up the organ system. These organs are gross in structure. The brain, heart, lungs, liver, and kidney are some examples of organs.
Human anatomy is mainly concerned with the study of the structure of internal organs and physiology is concerned with the study of the functioning of internal organs. The study of visceral organs is Splanchnology.
Types of organs in the Human Body
Altogether there are seventy-eight main organs within the human body. These organs work in coordination to give rise to multiple organ systems. Of these 78 organs, five are considered important for survival. These include the heart, brain, kidneys, liver, and lungs. If any of these five organs stop functioning even for a few seconds, death will occur without any medical intervention. Hence, it is always advised by doctors to keep our system healthy, maintain a balanced diet, get enough sleep, do regular physical activities and focus on healthy lifestyle changes.

The Largest organ in the human body
Based on the weight and length of the body parts, they are classified as the longest organs in the human body. These organs are macroscopic and are involved in many functions.
Altogether there are 10 large organs in the body, including the skin, liver, brain, lungs, heart, kidneys, spleen, pancreas, thyroid, and joints. Some of them are explained in detail below.
The skin is the largest external organ of the human body. It is an important organ and provides the outer covering, which protects from external elements. It also functions by protecting our internal organs from pathogens, regulates the temperature and pH of our body, prevents dehydration and also acts as the main sense organ. In both animals and humans, the skin acts as a barrier between the external and internal environments. The skin occupies an area of 19 to 20 square feet on the surface of our body. That is why it is called the largest external organ of the human body.
The liver is the largest internal organ in the human body, weighing between 1.3 and 1.5 kg. The liver is located in the upper right part of the abdomen and is the only organ found among vertebrates. It is triangular, bilobed in structure and has over 500 functions including blood clotting, protecting against invading pathogens, synthesizing hormones and proteins and secreting various enzymes and chemicals.
Major Body Parts
As discussed above, all 78 organs are important as they are associated with specific functions in our body. There are some organs, which are very essential for the survival of a person, so they are called major or important organs of the body. These organs are the hardest working organs in the human body, working 24 x 7.
It is the most complex part of our body. The human brain is located in our head and is surrounded by a strong bony structure called the skull and is suspended in a layer of fluid called cerebrospinal fluid, which functions by protecting the brain from minor mechanical shocks and shocks. . The brain, along with the spinal cord, composes the central nervous system. It is responsible for the thought, interpretation, regulation and control of the body’s movements.
The human heart is one of the most important organs in the human body. The human heart keeps on beating till the death of the person. On average, our heart beats seventy times per minute, which is close to forty-two hundred times per hour and pumps about 2,000 gallons of blood every day. Regarding position, the human heart is located in the thoracic cavity in the middle of the lungs, slightly to the left and behind the breastbone. Two-thirds of the heart is located on the left side of the chest, and the rest is balanced on the right side of the chest. The average size of an adult’s heart is equal to the size of our two hands fused and a child’s heart is about the size of a fist.
Humans have a pair of lungs, which are located within the thoracic cavity of the chest. The lungs play a major role in the respiratory system. In humans, a pair of lungs is structured in such a way that it facilitates the exchange of gases. They are lined by a thin membrane, the presence of bronchioles – small tubes, alveoli – a balloon-like structure and clusters of blood capillaries, which expand the surface area for the exchange of gases.
The pancreas is an important part of the human digestive system and is responsible for controlling blood sugar levels. It is an abdominal organ located behind the abdomen and surrounded by the spleen, liver and small intestine. It is also involved in the production of hormones such as glucagon, insulin, somatostatin and pancreatic polypeptide, and in secreting digestive enzymes such as protease, amylase and lipase in the duodenum.
The kidneys are an important part of the excretory system. They are bean-shaped structures located on either side of the spine and protected by the ribs and muscles of the back. It works by filtering out excess water and removing harmful toxins from the blood. Along with excretion, the kidneys also produce a hormone called renin, which regulates blood pressure.
The eye is a special sense organ that helps us to see the world around us. They are the visual sensory organs in our body, which are sensitive to light images. The human eye is different from the animal’s eye. In structure, it is a circular-shaped organ, enclosed within the eye socket in the skull and anchored below by muscles within the socket.
The small intestine is the longest part of the alimentary canal and is a part of the digestive system that runs between the stomach and the large intestine. It is narrower than the large intestine and is responsible for the absorption of nutrients from digested food, secretion of intestinal juices, bile juice from the liver and pancreatic juice from the pancreas.
FAQs on List of Organs in the Human Body
