Exocrine and endocrine parts of the pancreas
Illustration of the exocrine and endocrine (light blue) parts of the pankreas. Exocrine glands, unlike the endocrine ones, don`t secrete their products into the blood. The exocrine pancreas produces digestive juice, that are secreted into the small intestine via two ducts, which is regulated by hormones. Endocrine products are produced in the islets of Langerhans (light blue), including insulin and glukagon.
