What is glucagon?
Glucagon is a naturally occurring hormone that is produced in
the pancreas. The main function of glucagon is to react to a
situation where there is a low level of blood sugar present. The
release of glucagon into the bloodstream helps to restore blood
glucose levels back to a point that is considered acceptable for
the general function of the body. So, if the body has too much
insulin, as in the case of diabetes, the pancreas will emit
glucagon to attempt to stabilize everything.
Glucagon is a hormone, secreted by the Islets of Langerhans by Alpha Cell in Pancreas, that raises blood glucose levels. Its effect is opposite that of insulin, which lowers blood glucose levels
Glucagon is a hormone, I guess you meant "What gland secretes glucagon" The gland that secretes glucagon is Pancrea This hormone is absorbed by the body and turned into sugar to increase glucose in the blood. A blood glucose level below 80 is considered hypoglycemic and is very dangerous for diabetics, therefore must be treated with glucagon or glucagen.
What happens if I have too much glucagon? Rare tumours of the pancreas called glucagonomas can secrete excessive quantities of glucagon. This can cause diabetes mellitus, weight loss, venous thrombosis and a characteristic skin rash. What happens if I have too little glucagon? Unusual cases of deficiency of glucagon secretion have been reported in babies. This results in severely low blood glucose which cannot be controlled without administering glucagon. Glucagon can be given by injection…
Glucagon, yes. Cortisol, probably not. Glucagon raises blood sugar. Many type one diabetics own glucagon injectors, so that when their blood sugar goes too low they (or someone with them) can inject them with glucagon. Cortisol does raise blood sugar, but it is not used to raise blood sugar. It's used to treat many other diseases, but not the low blood sugar which type 1 diabetics sometimes get.
Glucagon is a hormone that works in conjunction with insulin. Both are produced in the pancreas, and are responsible for the storage/conversion of glucose in the body. Glucagon in particular encourages the soluble sugar glycogen to enter the blood, and also causes the conversion of glycogen to glucose.
Insulin and glucagon regulate the concentration of glucose in the blood. When the blood sugar is too high, insulin is released to trigger the absorption of glucose from the blood, to decrease the blood glucose concentration. When the blood glucose it too low, glucagon promotes the release of glucose into the blood. So, insulin and glucagon have an antagonistic relationship because although they are both responsible for returning the blood sugar to normal, insulin absorbs…
insulin and glucagon contol the blood glucose level....glucagon increase the blood glucose level and insulin decrease it....but glucagon also decrease the permeability of cells for glucose...so there is always a balance for these two hormones...glucagon is secreted by alpha cells of islets of langerhans and insulin by beta cells of islets of langerhans..
