What is Physiology?
Physiology (pronounced “fizzy-aw-low-jee”) is the study of life. Physiology helps us understand how the body works, from the smallest part (cells) all the way to the whole body. It helps us understand how different parts of the body work together. For example, the heart, lungs, and muscles must all work together perfectly to allow you to run and jump. Physiology also helps us understand how our body reacts to different conditions outside. Whether the weather is very hot or very cold, your body has ways to help the inside of your body stay at just the right temperature. Physiology helps us understand how living creatures do all the things they do: eat, sleep, run, jump, even breathe and keep their heart beating!

Questions Physiologists Ask

Physiologists are always trying to answer questions about how something works in the body in every day life, what changes when you are sick, and what changes when someone goes into a different environment, such as into space or deep into the ocean.
