What term describes the study of body structure?

• A. Anatomy
• B. Physiology
• C. Pathophysiology
• D. Homeostasis

Answer: (A)

Study of body structure is anatomy. It focuses on how the body's parts are built and arranged, from bones and muscles to organs, tissues, and even cells, and how they relate to one another in space. Anatomy can be explored at different levels, such as gross anatomy visible to the naked eye, as well as histology which looks at tissues under a microscope, along with surface and radiographic anatomy used in clinical settings. This emphasis on form distinguishes it from physiology, which asks how parts function and interact, while pathophysiology examines how disease alters structure and function, and homeostasis describes the body's mechanisms for maintaining a stable internal environment.
