GENERAL HISTOLOGY

Detailed explanation-1: -Through its various hormones, particularly glucagon and insulin, the pancreas maintains blood glucose levels within a very narrow range of 4–6 mM. This preservation is accomplished by the opposing and balanced actions of glucagon and insulin, referred to as glucose homeostasis.

Detailed explanation-2: -Glucagon. Glucagon is a hormone that works with other hormones and bodily functions to control glucose levels in the blood. It comes from alpha cells found in the pancreas and is closely related to insulin-secreting beta cells, making it a crucial component that keeps the body’s blood glucose levels stable.

Detailed explanation-3: -The human body wants blood glucose (blood sugar) maintained in a very narrow range. Insulin and glucagon are the hormones that make this happen. Both insulin and glucagon are secreted from the pancreas, and thus are referred to as pancreatic endocrine hormones.

Detailed explanation-4: -Insulin is a peptide hormone secreted by the cells of the pancreatic islets of Langerhans and maintains normal blood glucose levels by facilitating cellular glucose uptake, regulating carbohydrate, lipid and protein metabolism and promoting cell division and growth through its mitogenic effects.

Detailed explanation-5: -Insulin: It is secreted when the blood sugar level is high. It converts the glucose present in the blood into glycogen, a storage form of carbohydrate.
