Q

Functions of the pancreas

A

Exocrine: acinar cells secrete inactivated enzymes that travel to the small intestine and become activated to help digest carbohydrates, fats, and proteins
Endocrine: Islets of Langerhans cells regulate blood glucose levels through hormones like glucagon and insulin
