MICROANATOMY

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: -Insulin is the main regulator of sugar in the bloodstream. This hormone is made by beta cells and continuously released into the blood stream. Beta cells are found in the pancreas, which is an organ behind the stomach. Insulin levels in the blood stream are carefully calibrated to keep the blood glucose just right.

Detailed explanation-3: -Insulin lowers blood glucose levels by supplying the body with glucose and assisting cells in absorbing glucose. However, the pancreas releases glucagon when blood sugar levels are low. Blood sugar levels rise as a result of glucagon’s signal to the liver to release stored glucose.

Detailed explanation-4: -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.

Detailed explanation-5: -Insulin is normally secreted by the beta cells (a type of islet cell) of the pancreas. The stimulus for insulin secretion is a high blood glucose-it’s as simple as that. Although there is always a low level of insulin secreted by the pancreas, the amount secreted into the blood increases as the blood glucose rises.
