The endocrine system is made up of a network of glands. These glands secrete hormones to regulate many bodily functions, including growth and metabolism. Endocrine diseases are common and usually occur when glands produce an incorrect amount of hormones.
The endocrine portion of the pancreas produces hormones that are released into the circulatory system. The hormones are produced by specific cell types in the pancreas: alpha cells â glucagon, beta cells â insulin, and delta cells â somatostatin. The autonomic nervous system innervates these cells to release their hormones based on the bodyâs needs.
