Physiology is best defined as what?

• A. Behavioral science
• B. Physiology
• C. Anatomy
• D. Etiology

Answer: (B)

Physiology is about how living bodies function—the processes that allow organs and systems to work together, regulate activity, and maintain life. It covers the mechanisms behind energy production, circulation, respiration, digestion, and how nerves and hormones coordinate these functions to keep the body in balance (homeostasis). This is different from anatomy, which describes structure, etiology, which deals with causes of disease, and behavioral science, which studies behavior. So physiology is the best definition because it focuses on the working processes of the body.
