Anatomy is the branch of biology concerned with the study of the structure of organisms and their parts. Physiology is the scientific study of the normal function in living systems with a focus on how organisms, organ systems, organs, cells, and biomolecules carry out the chemical or physical functions in a living system. Anatomy and physiology make a natural pair of related disciplines that are often studied together.
