Which term is defined as the science dealing with the functions of living things or their organs?

• A. Aerobic
• B. Metabolism
• C. Addiction
• D. Physiology

Answer: (D)

Physiology is the study of how living organisms function and how their organs work together to keep the body alive. It explains how the heart pumps blood, how the lungs exchange gases, how muscles contract, and how systems like the nervous and endocrine networks coordinate activities. This focus on function distinguishes it from metabolism, which covers the chemical reactions that power those activities, and from terms like aerobic (relating to oxygen use) or addiction (a behavioral health issue).
