Pyloruskörtlarna

Pyloruskörtlarna, also known as pyloric glands, are a type of gastric gland found in the pyloric antrum of the stomach. These glands are primarily composed of mucus-secreting cells and endocrine cells. The mucus secreted by the pyloruskörtlarna plays a crucial role in protecting the stomach lining from the acidic environment and digestive enzymes.

Within the pyloruskörtlarna, various endocrine cells are present. These include G cells, which produce gastrin, a hormone that stimulates the secretion of gastric acid by parietal cells in other parts of the stomach. D cells are also found, secreting somatostatin, a hormone that inhibits the release of gastrin and other gastrointestinal hormones. Additionally, enterochromaffin-like (ECL) cells are present, which release histamine, further contributing to the regulation of acid secretion.

The specific composition and function of pyloruskörtlarna are important for maintaining gastric homeostasis. Their secretions help regulate the pH of the stomach and influence digestive processes. Disruptions in the function of these glands can be associated with various gastrointestinal disorders, highlighting their significance in overall digestive health. The pyloric glands are a key component of the stomach's complex secretory system.
