Physiological refers to the normal functions and processes of a living organism or its cells, tissues, and organs.
Physiological processes include breathing, circulation, digestion, hormone secretion, temperature regulation, and normal electrical activity of the nervous system. The term is often used in contrast to pathological, which describes abnormal changes associated with disease or injury.
However, “physiological” does not necessarily mean that something is harmless; a physiological response can sometimes contribute to problems when it is excessive, prolonged, or inappropriate for the circumstances.
COMMONLY CONFUSED WITH
- Pathological: relating to abnormal changes caused by disease or injury.
- Anatomical: relating primarily to the structure of the body rather than its functions.
