Which field studies body function?

• A. Physiology
• B. Anatomy
• C. Histology
• D. Biochemistry

Answer: (A)

Physiology focuses on how the body functions and how its systems work together to maintain life-supporting processes. It investigates mechanisms, regulation, and dynamic processes—like how the heart pumps blood, how neurons transmit signals, and how hormones coordinate activities—to keep everything running smoothly. Anatomy is about structure and location, histology studies tissues under a microscope, and biochemistry looks at chemical reactions in cells; none of these centers on how the body works as physiology does.
