endoteeliksi

Endoteeliksi is a Finnish term that translates to endothelium in English. The endothelium is the thin, smooth layer of cells that lines the inner surface of all blood vessels and lymphatic vessels. It also forms the inner lining of the heart chambers. This single layer of cells, known as endothelial cells, plays a crucial role in maintaining vascular health and regulating various physiological processes.

The endothelium is far from being a passive barrier. It actively participates in numerous functions, including regulating blood pressure through the production of vasodilators and vasoconstrictors, controlling blood clotting by influencing the balance between procoagulant and anticoagulant molecules, and mediating inflammation by interacting with immune cells. It also plays a vital role in the transport of nutrients and waste products between the blood and the surrounding tissues.

Damage or dysfunction of the endothelium, often referred to as endothelial dysfunction, is an early indicator and contributor to many cardiovascular diseases, such as atherosclerosis, hypertension, and stroke. Factors like high cholesterol, smoking, diabetes, and inflammation can impair endothelial function. Maintaining healthy endothelial cells is therefore paramount for overall cardiovascular health. Research continues to explore the complex functions of the endothelium and its implications in various diseases.
