physiology. 1  the branch of biology dealing with the functions and activities of living organisms and their parts, including all physical and chemical processes. 2  the organic processes or functions in an organism or in any of its parts.
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.
