THE PANCREAS

The pancreas is a vital organ with both exocrine and endocrine functions, playing a key role in digestion and hormonal balance. It produces digestive enzymes and hormones like insulin and glucagon, essential for regulating blood glucose levels. Located retroperitoneally, behind the stomach and below the liver, the pancreas consists of the head, body, and tail, with the pancreatic duct connecting to the duodenum. Learn about the intricate relationship between insulin and glucagon, and their impact on metabolism and overall health.
