Which organ produces insulin?

Explanation:
Insulin is produced by the endocrine tissue of the pancreas, specifically the beta cells in the islets of Langerhans. When blood glucose rises, these cells release insulin into the bloodstream, signaling muscle and adipose tissue to take up glucose and promoting the liver to store glucose as glycogen while reducing glucose production. The pancreas handles both endocrine (hormone) and exocrine (digestive enzyme) roles, but insulin comes from the pancreatic beta cells. The liver, stomach, and kidneys do not produce insulin.
