endoteeliä

Endoteeliä refers to the endothelial cells that form the inner lining of blood vessels and lymphatic vessels. These cells form a single layer, known as the endothelium, which plays a crucial role in maintaining vascular health and function. Endothelial cells are highly active and participate in a wide range of physiological processes. They act as a barrier, controlling the passage of substances between the blood and surrounding tissues. Furthermore, they are involved in regulating blood clotting, the immune response, and the tone of blood vessels through the production of various signaling molecules. The endothelium also has a critical role in wound healing and the formation of new blood vessels, a process called angiogenesis. Dysfunction of the endothelium is implicated in various diseases, including atherosclerosis, hypertension, and diabetes.
