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 concentration of glucose in the blood is regulated by the action of the hormones insulin and glucagon . These hormones are made in the pancreas and act on cells in the liver. The liver acts as the body’s glucose ‘reservoir’.

Detailed explanation-4: -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-5: -When a person’s blood sugar is too high, their pancreas secretes more insulin. When their blood sugar levels drop, their pancreas releases glucagon to raise them. This balance helps provide sufficient energy to the cells while preventing damage that can result from consistently high blood sugar levels.
