Introduction to Knowing Human Body:
The human body is composed of many parts, each of which serves a special function. Human bodies vary a little from person to person, not only in the visible aspects of size and shape but also in the placement of internal organs.

The human body refers to the entire structure of a human being and comprises a head, neck, trunk (which includes the thorax and abdomen), arms and hands, legs and feet. Every part of the body is composed of various types of cell.

Standing Properly :
Avoid slouching. Straighten your body and pull your shoulders back so that your legs, torso, neck and head are all in a vertical line.
The sense organs:
Eyes, ears, tongue, skin, and nose — help to protect the body. There are five senses – sight, smell, touch, taste and hearing.Our senses help us to understand what’s happening around us.
Skin is the largest organ in the body. Skin is made of many layers of cells. It protects the various body systems by keeping germs and water out, and body fluids and salt in. Skin helps keep our bodies at the right temperature and is the sense organ for touch.
Sight : The sense of sight helps us recognize each other and learn about color, motion and distance.
Hearing : The sense of hearing helps us learn from each other through communication. Sound can produce patterns.
Smell : The sense of smell helps us enjoy life and helps us learn about unsafe conditions.
Taste : Taste helps us, among other things, to select and enjoy food. There are four familiar tastes.
