What is the study of function?

• A. Anatomy
• B. Physiology
• C. Osteology
• D. Scull

Answer: (B)

Physiology is the study of how the body's parts function and interact. It explores processes, mechanisms, and regulation that keep the body alive and healthy—like how the heart pumps blood, how the lungs exchange gases, and how kidneys filter waste and maintain balance. Anatomy, in contrast, focuses on structure—what parts look like and where they are. Osteology is the study of bones, and the skull is a specific bone structure rather than a field of study. Since the question asks about the study of function, physiology is the best fit because it specifically explains how the body's systems work together to maintain life.
