Which term means the study of the functions of the body?

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

Answer: (D)

Physiology is the study of how the body functions—the processes and actions of organs and systems that keep us alive and working, such as circulation, respiration, digestion, and metabolism. This focus on function explains how the skin responds to stimuli, how blood flow and nerve activity influence appearance and sensation, and how glands and hormones affect skin health. Anatomy looks at structure, histology examines tissues under the microscope, and cytology studies individual cells, but only physiology directly addresses how the body's parts operate together.
