Cell Physiology

Cell physiology (including cellular electrophysiology) is the biological study of the cell's mechanism and interaction in its environment. The term "physiology" refers to all the normal functions that take place in a living organism. Absorption of water by roots, production of food in the leaves, and growth of shoots towards light are examples of plant physiology. The heterotrophic metabolism of food derived from plants and animals and the use of movement to obtain nutrients (even if the organism itself remains in a relatively stationary position) are characteristic of animal physiology.

In the context of human physiology, cell physiology is often the term used to describe the physiology of membrane transport, neuron transmission, and (less frequently) muscle contraction. In general these cover the digestion of food, circulation of blood and contraction of muscles and, therefore, are important aspects of human physiology. For a more complete description of the general physiological function of human cells (as well as the cells of other life forms), see the article on cell biology
