PHYSIOLOGY

Physiology  is the area of science that helps understand how your body’s systems function when they are healthy and sick. When working well, your lungs help transport gas from the air into your bloodstream. (Yodiyim/Dreamstime)

Physiology is the study of how the human body works. It describes the chemistry and physics behind basic body functions, from how molecules behave in cells to how systems of organs work together
It helps understand what happens when your body is healthy and what goes wrong when you get sick.

Most of physiology depends on basic research studies carried out in a laboratory. Some physiologists study single proteins or cells, while others might do research on how cells interact to form tissues, organs, and systems within the body. Pathophysiology is a science within physiology. It is the study of the changes in the body that are the cause or effect of injuries or diseases.
