The human is the most unique of all living things on this Earth. Not only is the human body made up of skin, muscles, bones, nerves, blood and hair but also brains!
Our body consists of various special organs such as the eyes, the ears, and the nose.
The base unit of any living body is a cell. Numerous cells combine together to form a special part of the body. Thus, we have
The lungs through which we breathe;
The heart that pumps the blood;
Stomach, intestines, liver, pancreas that digest food;
The kidneys that form urine
And the brains to work that all out.
The human body is such a sophisticated machine that works in harmony and performs complex activities without any programming (unlike a computer).
