Which gland secretes insulin?

Explanation:
Insulin is produced by the pancreas, specifically by the beta cells in the islets of Langerhans. When blood glucose rises, these cells release insulin, which helps body cells take up glucose from the bloodstream and signals the liver to store glucose as glycogen, lowering blood sugar. The other glands listed do not secrete insulin: the adrenal gland releases hormones like adrenaline and cortisol, the pituitary releases various hormones such as growth hormone and TSH, and the testes produce testosterone.
