Which field studies the function of the body, while anatomy studies its structure?

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

Answer: (D)

Physiology focuses on how the body works—the functions and mechanisms of organs and systems and how they’re regulated to maintain stability. It asks how the heart pumps blood, how nerves transmit signals, and how kidneys control fluid balance, often using ideas like homeostasis and feedback to show how different parts interact. Anatomy, by contrast, maps what the body looks like and how its parts are arranged. Biochemistry dives into the chemical reactions inside cells, while histology studies tissues under the microscope. So when the question asks which field studies function while anatomy studies structure, physiology is the best fit.
