Päähaimankanava

Päähaimankanava, also known as the pancreatic duct or duct of Wirsung, is a vital anatomical structure within the human digestive system. It originates in the tail of the pancreas, a gland located behind the stomach, and travels through the body of the pancreas, eventually merging with the common bile duct. The primary function of the päähaimankanava is to transport digestive enzymes produced by the pancreas to the duodenum, the first part of the small intestine. These enzymes play a crucial role in breaking down carbohydrates, proteins, and fats, facilitating nutrient absorption. The pancreatic duct is a thin, tubular structure, and its diameter can vary slightly between individuals. It is lined with epithelial cells that secrete bicarbonate, which helps to neutralize the acidic chyme entering the duodenum from the stomach. In some individuals, an accessory pancreatic duct, known as the duct of Santorini, may also be present, draining a portion of the pancreas directly into the duodenum, sometimes bypassing the main duct. Blockages or inflammation of the päähaimankanava can lead to serious medical conditions such as pancreatitis, a painful inflammation of the pancreas.
