Human Body - Urvish Singh

History: According to modern biology and evolutionary theory, we evolved from creatures similar to chimpanzees about 5 to 10 million years ago. About 3 million years ago, we started walking upright, but the brain was not much developed. 

Latest genetic studies indicate that we may have originated from a group of people in eastern and southern Africa about 150,000 years ago.

Our body consists of about 724 trillion cells, as we have a highly developed organ system consisting of 78 organs in which 5 are vital for survival, which is as follows heart, liver, kidney, lungs and brain. Like other mammals, we are sensitive towards our surroundings and caring.
