What is Physiology?
In essence Physiology is the study of how the body works. This includes how organ systems, organs, cells, and bio-molecules carry out the chemical or physical functions that exist in a living system. Have you ever wondered why athletes often train at altitude, why your heart rate increases before an exam or why you can hold your breath for a longer time if you breath hard for a few minutes before hand? Physiology has the answers to all these questions and more!
