Which gland produces insulin and glucagon that raise and lower blood glucose levels?

Explanation:
Regulation of blood glucose relies on two opposing hormones produced by the endocrine pancreas. The pancreas contains the islets of Langerhans, where alpha cells secrete glucagon and beta cells secrete insulin. Insulin lowers blood glucose by helping cells take in glucose, promoting storage as glycogen in the liver and muscles, and reducing hepatic glucose production. Glucagon raises blood glucose by signaling the liver to break down glycogen and to synthesize new glucose (gluconeogenesis). This coordinated action keeps blood sugar within a narrow range. The other glands listed don’t produce these two hormones, so the gland responsible for insulin and glucagon is the pancreas.
