There are as many as 80 organs which form groups and work in coordination with one another to accomplish a particular task.

A group of organs assigned to complete a specific function, on the other hand, is called an organ system. For example, heart, blood, blood vessels and lungs are the major components of the blood circulatory system.

Do you know how many organ systems are there in your body? Well, there are nearly a dozen organ system, each made up of multiple individual organs working in coordination with one another. At the same time, there is coordination and linkage between different organ systems which combine to form an individual.

Among them, brain, heart, lungs, liver and kidneys are considered as the major or vital organs of the human body. The master organ, the brain, serves as CPU or control center, while beating of heart is considered as the sign of life in an individual. The lungs assist in the supply of oxygen to every individual cell and the removal of carbon dioxide outside the body. The liver attaches with itself at least three superlative degrees, i.

Kidney serve as an important component of the excretory system which is responsible for the removal of the excess, unnecessary materials from the body fluids. All the organs of the body are not essential for the survival of an individual.

There are certain organs, like arms, legs, stomach, large intestine, and tongue the complete removal of which will not put your life at risk.

The other organs, like brain, heart, kidney, lungs and pancreas, etc. They are called the major or vital organs of your body.

You can have a bird eye view of the shape, size and functioning of the major body organs through the following description:. Lying on the top of the body and enclosed in an incredibly hard protective cover of skull, the brain serves as the control center for all the functions of the body.

Nearly 1. Just like the brain of other mammalian species, it is distinguishable into three basic divisions of forebrain, midbrain and hindbrain. In absolute terms, the human brain is smaller than those of large mammals, like whales and elephants. But, when you take into account the measure of relative brain size, it happens to be twice as large as that of the bottlenose dolphin. One of the most vital organs in the body, the heart is assigned the role of pumping blood with such a force that it reaches every individual cell.

The blood carries with it nutrients as well as oxygen which are to be delivered to all the cells. Another important function of blood is to transport waste substances and gases for elimination out of body. Measuring 5 inches in length, 3. There are four chambers in it, with the upper two being atria and the lower ones termed as ventricles.

Lungs are the respiratory organs as they are involved in the exchange of gases. They are found in the chest region on either side of the heart. The major tubular branches are called bronchi which gradually divide into bronchioles and alveoli — the smallest air sacs with single cell lining.

The primary role assigned to them is the extraction of oxygen from the atmospheric air and release carbon dioxide from the body. Since ancient times man has been trying to find the answer to this question. In Egypt, an attempt was made to learn about human organs due to coating on dead bodies. On the other hand, the earliest studies about the human body are found in China. Now after thousands of years, how much science has found the answer to this question?

First of all, it is a matter of understanding what is the meaning of an organ according to science? A group of tissues is called an organ.

You will find this definition in science books after primary school. According to science, every organ works to increase the capacity of your body and save survival. Brain, heart, liver, at least one kidney and one lung are vital organs i. There are many other organs that can be lived without or can be changed with the help of modern science.

Now know how the number of organs is fixed. Experts believe that the total number of organs in the human body depends on whom you ask or how you count. See, there are bones in the human body, now if you consider a bone as an organ, then the number will be very high, according to a report published by Live Science, the number of organs in the human body is generally considered to be This game is endless.

The list of 78 counts the nerves just once, but there are trillions of them. Lee often tells her medical and graduate school students to be OK with this type of ambiguity. However you count them, you should take care of the organs you do have, she added. After all, the body only has so many performers at its organ recital.
