mavekirtlerne

Mavekirtlerne, often translated as "stomach glands," refers to the specialized cells and structures located within the lining of the stomach. These glands are crucial for the digestive process, producing various secretions that aid in breaking down food and protecting the stomach itself. There are several distinct types of mavekirtlerne, each with a specific function.

The cardiac glands are found near the esophagus and primarily secrete mucus, which serves as a protective barrier against stomach acid and mechanical abrasion. The fundic glands, located in the main body of the stomach, are the most numerous and complex. They contain parietal cells, responsible for producing hydrochloric acid (HCl), and chief cells, which secrete pepsinogen. Hydrochloric acid creates an acidic environment essential for the activation of pepsinogen into pepsin, a powerful enzyme that begins the digestion of proteins.

Pyloric glands, situated near the small intestine, produce mucus and hormones. Notably, they contain G cells that secrete gastrin, a hormone that stimulates the secretion of gastric acid by parietal cells. This intricate interplay of secretions from the different mavekirtlerne ensures efficient and controlled digestion within the stomach. The integrity and function of these glands are vital for overall digestive health.
