Pancreas

The pancreas is a vital organ in the human body located behind the stomach and plays a crucial role in digestion and the regulation of blood sugar levels.

Anatomy of the Pancreas

The pancreas is a glandular organ with both exocrine and endocrine functions. It is divided into three main regions: the head, body, and tail. The head of the pancreas is connected to the duodenum (the first part of the small intestine) and the tail extends to the spleen.

Exocrine Function

The exocrine function of the pancreas involves the production of digestive enzymes and bicarbonate, which are released into the small intestine to aid in the digestion of carbohydrates, proteins, and fats.

Endocrine Function

The endocrine function of the pancreas involves the production of hormones such as insulin and glucagon, which are crucial in the regulation of blood sugar levels. Insulin helps lower blood sugar levels, while glucagon helps raise them when needed.
