Category:Subject:Physiology. Books in this subject area deal with physiology: the study of the mechanical, physical, and biochemical functions of living organisms. Physiology has traditionally been divided between plant physiology and animal and all living things physiology but the principles of physiology are universal, no matter what particular organism is being studied.
Physiology is the study of how organisms function. The physi-part of the word comes from a Greek word that is broadly translated as 'natural origin.' The same root is used to form the words physician, physical, and physics. When we think of physics today we think of the study of how matter and energy work, but another way to think about physics is as a study of how nature functions. In that sense, physiology is also a study of how nature functions - in this case, within a living organism.
