Anatomy is the study of the structure of the body. It covers the microscopic and macroscopic structure of the body and how body parts develop. Anatomy also examines the relationship between structure and function. The study of anatomy includes looking at body systems, regions, external features, and using imaging technologies. Physiology is the study of function in living organisms. The goals of physiology are to understand how the body responds to stimuli and maintains stable internal conditions despite external changes. Anatomy identifies and describes body structures, while physiology examines their functions.
