# Anatomy & Physiology: Form and Function --- **Anatomy and physiology** are a pair of closely related studies in [[biology]] related to the study of the parts of the human body (anatomy) and their functions (physiology). [[Anatomy]] is the study of the bits and pieces of the body, their forms and functions; **physiology** is the study of the processes and functions of living things. These fields are inextricably intertwined—neither can be adequately understood if not with some understanding of the other. ## Biological Organization The subjects of anatomy & physiology is broken down and in a series of increasingly complex organizational levels, starting with atoms and finishing with a whole organism. - [[chemistry|chemical]] - [[cell|cells]] - [[tissue|tissues]] - [[organ|organs]] - [[organ system|organ systems]] - [[biology|organism]] ___
