insulin
insulin f

Insulin is a hormone secreted by the islets of Langerhans in the pancreas of vertebrates. Insulin regulates the process of converting glucose into glycogen in the liver. If the blood glucose concentration is high, the rate of insulin secretion is high, which accelerates the conversion of glucose into liver glycogen. If the blood glucose concentration is low, insulin secretion decreases, which is an example of the feedback regulation that exists in many hormones. A person suffering from diabetes does not produce enough insulin to balance the exact level of glucose in his body.

Involuntary (smooth) muscles. Muscles are associated with tissues and internal organs, such as the gut and blood vessels.

Involuntary muscle actions include constriction of the pupil, dilation by the iris, and peristalsis. See antagonistic muscles and voluntary muscles.
