Pancreas in situ

Learning objectives

After working through this study unit you will be able to:

  1. Describe the structure and function of the pancreas.
  2. Understand the relations of the pancreas to the nearby structures and organs.
  3. Distinguish the neurovascular supply to the pancreas.

Watch videos

The pancreas is an accessory retroperitoneal organ of the digestive system that has both exocrine and endocrine functions. It helps digestion by producing pancreatic juices which are secreted into the duodenum. These juices consist of enzymes that break down sugars, fats, and starches. The pancreas also produces important hormones (insulin, glucagon, and somatostatin) that regulate blood sugar levels.

The following video will help you learn everything you should know about the pancreas, its anatomy, function, relations to surrounding structures and clinical importance.
