Sugar level in humans is regulated by "Insulin" and "glucagon" hormones that are secreted by the pancreas. Both hormones work in a balanced way to regulate the blood sugar level within a specific range if the sugar levels spike or drop.
Together,<u> </u><em><u>insulin and glucagon help maintain a state known as homeostasis</u></em><em>.</em> By definition, homeostasis is the maintenance of the internal environment of cell/body with respect to the external environment. Thus, homeostasis maintains a relatively stable state that persists despite changes in the world outside.<u> When blood sugar is too high, the pancreas secretes more insulin which acts to trigger breakdown of sugar thus reducing its level. By contrast, when blood sugar levels drop, the pancreas releases glucagon to allow conversion of macromolecules to simple sugars and raise its level.</u>
Use of transgenic animals to improve human health and animal production. ... The advance in the generation of pigs to be used as the source of organs for patients and in the preparation of pharmaceutical proteins from milk and other possible biological fluids from transgenic animals is described.
