Little Scientists Magazine N.14

Have you ever wondered what’s inside you? Your body is made up of many separate parts, called organs. Each of them has a specific function, or job, necessary for everyday living.

The study of these systems and their functions is called physiology. The Greek scientist Hippocrates was the first to study physiology more than 2,400 years ago. But it was not until 1838, when scientists discovered that the body was made up of tiny individual cells, that real advances in physiology, and therefore medicine, were made.
