The idea or concept of “homeostasis,” dates all the way back to the 1800s and has evolved ever since then. In the 1800s, Claude Bernard came up with the term, “milieu intérieur.” In French, “milieu” is defined as environment, whereas “intérieur” is a term meaning inside; coupled together, it has a collective meaning of internal environment. In the early 1900s, physiologist, Walter B. Cannon took Claude Bernard’s concept of “milieu intérieur,” and developed it even further as the concept of “homeostasis.” Cannon described homeostasis as the maintenance of a stable and steady internal environment and the astonishing physiological processes by which it is regulated. An example of the detection of homeostasis can be seen in the regulation of blood glucose levels. Insulin transfers glucose from the blood stream into cells and takes glucose and stores it as glycogen. It also effectively reduces blood glucose. Glucagon, its antagonist, converts hepatic glycogen into glucose, increasing blood glucose levels. When blood glucose levels are too high, pancreas β-beta cells release insulin, which will stimulate uptake of glucose into cells, resulting in a reduction of blood glucose levels. On the other hand, when blood glucose levels are too low, pancreas α-alpha cells will release glucagon, stimulating gluconeogenesis. This will, in turn, increase blood glucose levels until they are at an optimal state. When there are malfunctions with insulin function, diabetes
