Which field of study focuses on the physical structure of the body and its systems?

• A. Anatomy
• B. Physiology
• C. Pathophysiology
• D. Planes of the Body

Answer: (A)

Anatomy is the study of the body's physical structure and how its parts are organized into systems. It looks at where bones, muscles, organs, and tissues lie and how they fit together to form the whole body. This structural focus is why anatomy is the best fit for the question, since the inquiry is about the body's physical layout. In contrast, physiology investigates how the parts work and interact, pathophysiology explores how disease alters function, and planes of the body refer to reference views used to describe locations rather than a field of study.
