Anatomy & Physiology

This section includes articles on Anatomy, which deals with the structure and organization of living things at the cellular, tissue, and organ level, and Physiology, which studies the mechanical, physical, and biochemical functions of living organisms. It is not uncommon for Physiology to be associated with Anatomy since structure and function are mostly inseparable topics particularly at the cellular and molecular level.
