What does physiology study?

• A. The structure of body parts and their relationships to one another.
• B. The genetic makeup of the organism.
• C. The function of the body, how parts work.
• D. The development of tissues.

Answer: (C)

Physiology is the study of how the body functions—how its parts work together to carry out the processes that keep us alive. It looks at the mechanisms behind activities like how the heart pumps blood, how muscles contract, how nerves transmit signals, and how kidneys regulate fluids and electrolyte balance. By exploring these functions and their regulation—such as feedback loops and homeostasis—we understand not just what organs are, but how they operate and interact in living systems. The other areas describe different aspects: the structure and relationships of body parts (anatomy) focus on form, not function; the genetic makeup (genetics) deals with inherited information; and the development of tissues (histology or developmental biology) looks at how tissues form and grow. So physiology centers on the functional side—the why and how behind bodily processes.
