Your Amazing Body

Your body is made up of hundreds of different parts. You

probably know the names of the parts you can see, but there

are many more hidden deep inside you.

Body parts often come in pairs. You have two feet, two eyes,

two ears, two lungs, and so on. This means you have a spare

in case one of them gets damaged.

Water is the most important chemical in your body. About

two-thirds of your weight is water.
