''Human Body-Body building body''

The human body is amazingly complicated.

It is made up of hundreds of different organs,

tubes, tendons, tissues and other body parts

each with its own job to do. In turn these

parts are made up of millions of microscopic

units called cells. Inside cells are the smallest

body parts of all the genes that make us

human. They tell cells how to do all the

things they need to do to make our bodies

work and keep us alive.
