By George Thompson Our body holds a dynamic structure. It is everything that makes a human being. Head, neck, arms, torso, and legs are the main parts of the human body. It consists of a number of biological systems that carry out specific functions. Our body is made up of numerous cells. The nerve cells in the human brain are 100 billion in number. 70% of the body is made up of water.
Let us have a look at the interesting features of our body and their functioning.
Human Brain
It controls all the functions of the human body. It receives and sends signals from and to different organs of the body and is responsible for thoughts, feelings, and memory.
Human Heart
It is the blood pumping organ of the body. It pumps and circulates blood and oxygen throughout the body.
Kidneys
All the waste from the body is removed by the kidneys. The important nutrients are reabsorbed by the body while the waste is removed in the form of urine.
Liver
The liver detoxifies harmful chemicals, filters the blood, secretes bile, and produces blood clotting proteins.
Lungs
Their main function is to inhale oxygen and exhale carbon dioxide. The inhaled oxygen is also transferred to the cells via blood.
Sense Organs
Eyes, ears, nose, tongue, and skin are the main sense organs of the human body. The eye functions as the organ of sight. The ears are meant to hear, nose to smell, skin senses touch, while the tongue is to taste. These sense organs respond to external stimuli by sending signals to the nervous system.
Thus we see how diverse a human body is. A single organ stops functioning, and it has a drastic effect on body functions. That is why it is advised to keep your body healthy and mind sane.
