- #113 The Control Of Blood Glucose
The blood glucose concentration is regulated by negative feedback control mechanisms. Blood glucose concentration should remain at a fairly constant value of about 100 mg glucose per 100 cm3 of blood. If blood glucose concentration falls well below...

Osmoregulation is the control of the water content of body fluids. It is part of homeostasis, the maintenance of a constant internal environment. It is important that cells are surrounded by tissue fluid of a similar water potential to their own...

Origin: Anc Greek

+???????/ecrino(=to secrete)>??/ec>(=prefix meaning ?out?, ? from?) + ?????/crino(=to judge, to separate)
Coined/History
Claude Bernard, in 1855 was first who used for the term ?internal secretion? in order to describe the release of glucose from liver glycogen. Ernest Starling (1866?1927) who coined the term ?hormone? defined also the term of ?endocrine? to contrast the actions of hormones secreted internally (endocrine) with those secreted externally (exocrine) or into a lumen, such as the gastrointestinal tract.
Definition
Endocrine is the type of signaling in which a hormone secreted by a cell into the blood and carried by blood and tissue fluids to the cells they act upon.
