endotelialne

Endotelialne refers to the endothelium, which is a type of tissue that forms the inner lining of blood vessels, lymphatic vessels, and the heart. It is a single layer of flattened cells called endothelial cells. These cells play a crucial role in maintaining vascular homeostasis and regulating various physiological processes.

The endothelium acts as a selective barrier, controlling the passage of substances between the blood and the surrounding tissues. It participates in processes such as blood clotting, inflammation, and the formation of new blood vessels (angiogenesis). Endothelial cells also produce a variety of signaling molecules, including nitric oxide, which helps to regulate blood pressure and blood flow. Dysfunction of the endothelium is implicated in a number of diseases, including atherosclerosis, hypertension, and diabetes. The integrity and function of the endothelium are therefore critical for overall cardiovascular health.
