Infographic : What is my body made from?

It takes about 100 trillion (100,000,000,000,000) microscopic living units called cells to make a human body. There are many different types of cells, and these are organized into the tissues and organs that make up your major body systems. These include the skeletal and muscular systems, which support and move the body, and the digestive and respiratory systems, which supply food and oxygen.
