Human body is like a wonderful machine. It is unique and the most amazing machine in the world. It is capable of doing many things that no other machine can do.
Human beings are also living things. The human body is made up of bones, blood, nerves and muscles. The outer covering of the body is the skin.
The body consists of different kinds of cells. Cells are the basic building blocks of the body. A group of cells join together to makes a tissue.
A group of tissues together make an organ. Organs are our body parts. Organs are external as well as internal. Each one does some special work. We have many parts in our body which work together. Different parts of our body are our hands, eyes, legs, nose, chest, knee, foot, etc. The organs or groups of organs help us to work, play, grow, feel, see, digest our food and so on.
