A human body is combination of different body parts. When these parts join together they make a human body. It consists of internal and external organs. Major internal organs are heart, brain, stomach and intestines whereas major external organs are scalp, eyes, nose, hands, feet, arms and legs. A human body is said to be the most complex thing on earth which is very difficult to understand and highly difficult to cure. At the same time it is simple because, for the purpose of proper working, it requires really simple input (food and water) only three times a day! Because of these and some other features, a human’s body has been the center of interest for centuries and still its exploration is on its way…
