Negative feedback: the diminution or counteraction of an effect by its own influence on the process giving rise to it, as when a high level of a particular hormone in the blood may inhibit further secretion of that hormone, or where the result of a certain action may inhibit further performance of that action.
homeostasis: the tendency of a system, especially the physiological system of higher animals, to maintain internal stability, owing to the coordinated response of its parts to any situation or stimulus that would tend to disturb its normal condition or function.
(1).Examples of negative feedback: blood glucose level rises as meal is digested and nutrients pass through small intestine into blood.
(2).Examples of negative feedback: blood glucose level drops as glucose is used to make (ATP, Energy).
