A few words of thanks would be greatly appreciated.

Physiology - Definition


Physiology is a sub-field of biology that studies how different living organisms function. In more precise terms, this field aims to understand how the body works, what roles each organ and their processes play, what different substances are present in the body, and so on. Yet this discipline also assesses the function and place of each living thing in its environment, including their position on the food chain, their influence on their environment, how they interact with other living things, and more. Moreover, the adjective physiological is used in medicine to define a function that is performed normally, such as the physiological appearance of pubic hair during puberty. In this context, it is the opposite of pathological.
