Which sub-discipline is primarily concerned with the study of body systems and their functions?

• A. Anatomy
• B. Biometrics
• C. Physiology
• D. Neuroscience

Answer: (C)

Physiology is the study of how body systems work together and regulate their functions. It looks at the mechanisms behind processes like how the heart pumps, how lungs exchange gases, how digestion and metabolism operate, and how hormones and nerves coordinate responses to maintain balance. This functional focus across the whole body is why physiology is the best fit for studying body systems and their functions. Anatomy, by contrast, centers on the structures themselves; biometrics involves measuring biological data, often for identification or health assessment; and neuroscience concentrates specifically on the nervous system and its processes.
