Which term is the study of the functions of the human body?

• A. Physiology
• B. Organelle
• C. Spinal Cavity
• D. Planes

Answer: (A)

Physiology is the study of how the body functions and how its systems work together to keep you alive. It looks at processes like how the heart pumps blood, how the lungs exchange gases, how nerves control movement, and how muscles respond to signals. That focus on functioning and mechanisms is why physiology is the best fit. Other terms refer to different things: an organelle is a tiny structure inside a cell, not the whole body's functions; a spinal cavity is an anatomical space inside the spine, and planes are imaginary reference lines used to describe body sections rather than to study function. Understanding the distinction helps you see why physiology specifically deals with how the body works.
