Physiology (/ˌfɪziˈɒlədʒi/; from Ancient Greek φύσις (phúsis) ‘nature, origin’, and -λογία (-logía) ‘study of’) is the scientific study of functions and mechanisms in a living system. As a sub-discipline of biology, physiology focuses on how organisms, organ systems, individual organs, cells, and biomolecules carry out the chemical and physical functions in a living system. According to the classes of organisms, the field can be divided into medical physiology, animal physiology, plant physiology, cell physiology, and comparative physiology.
