Overview of Human Physiology
Human physiology is the branch of biology that deals with the functions and mechanisms of the human body. It involves studying how the various systems work both independently and in concert to maintain homeostasis, the body’s state of equilibrium. Understanding human physiology is crucial for students of medicine, nursing, and other health-related fields, as it lays the foundation for more advanced topics such as pathophysiology and pharmacology.
