Human anatomy is the study of the body’s structures, while physiology is the study of how those structures work together to support the functions of life. Anatomy is about the structure, location, and organization of different parts of the body, while physiology studies the inner functioning of cells, tissues, and organs. Together, anatomy and physiology explain the structure and function of the different components of the human body to describe what it is and how it works. Anatomy and physiology are two of the most basic terms and areas of study in the life sciences. Anatomy refers to the internal and external structures of the body and their physical relationships, whereas physiology refers to the study of the functions of those structures.
