Physiology is the science that studies how the human body works.
It explains the physics and chemistry behind basic body functions, such as how molecules behave in cells and how organ systems work together.
It enables us to comprehend what occurs in a healthy body in everyday life and what goes wrong when someone becomes ill.
Human physiology:
Human physiology is a branch of animal physiology and life science.
It is the study of how the body's systems function in a healthy state, and this examination of function is frequently done at the cellular level, not of single cells but of how cells collaborate to produce a normal state of operation.
Basic human physiology investigates how the body's systems function normally and predictably, whereas pathophysiology investigates how natural body systems develop illness in order to gain insight into how diseases can be treated.
