ANATOMY

Detailed explanation-1: -Insulin is secreted primarily in response to glucose, while other nutrients such as free fatty acids and amino acids can augment glucose-induced insulin secretion. In addition, various hormones, such as melatonin, estrogen, leptin, growth hormone, and glucagon like peptide-1 also regulate insulin secretion.

Detailed explanation-2: -When we eat food, glucose is absorbed from our gut into the bloodstream, raising blood glucose levels. This rise in blood glucose causes insulin to be released from the pancreas so glucose can move inside the cells and be used.

Detailed explanation-3: -When blood glucose levels rise, beta cells in the pancreas normally make the hormone insulin. Insulin triggers cells throughout the body to take up sugar from the blood.
