endothelium of heart

The heart wall is composed of connective tissue, endothelium, and cardiac muscle. The heart wall is divided into three layers: epicardium, myocardium, and endocardium. The endothelium weighs approximately 1 kg in the average patient and covers a total surface area of 4000 to 7000 square meters. The layer assists in the regulation of mechanisms involved in blood clotting. The endothelium is vital to the proper functioning in the heart, in particular due to its production of nitric oxide (NO) which regulates vascular tone. Far from being inert, it is metabolically active and produces a variety of vasoactive mediators. Because it is adjacent to the bloodstream, the endothelium can signal a blood vessel’s muscle to respond to changes in pressure and inflammation. The endothelium is … The endothelium is a thin membrane that coats the inside of blood vessels and the heart. The endothelium is a layer of cells on the inside of blood vessels and the heart. Furthermore, this tissue has an embryonic mesodermal origin. Also, it lines the heart cavities. The endothelial layer has a tone that contributes to the control of blood pressure. The endothelium, which forms the inner cell lining of all blood vessels and lymphatics in the body, is a spatially distributed organ. Damage to the endothelium contributes to the development of atherosclerosis, and hence to possible myocardial infarction and subsequent heart failu … It is the cardiac muscle that enables the heart to contract and allows for the synchronization of the heartbeat. Epicardium: the outer protective layer of the heart. It plays a number of roles that are important for the functioning of the cardiovascular system. Endothelium cells help to control toxic substances in the blood. Endothelia are considered the “brains” of blood vessels. The vascular endothelium is a monolayer of cells between the vessel lumen and the vascular smooth muscle cells. Endothelium is a specialized type of epithelium found in the lining of blood and lymphatic vessels. Branches of the heart’s conduction system are immersed into the subendocardial layer. As mentioned earlier the endothelial cells do a lot more than just regulate blood flow with nitric oxide, so damaging them has many other consequences. Damaged endothelium therefore contributes to hypertension. The tone of the endothelial layer also determines how much work is needed from the heart to pump blood through the body. The inner layer lines the heart chambers and is made of endothelial cells. Damage to the cardiovascular endothelium not only develops with heart disease, but is one of the first steps on the path to heart disease, detectable even before structural changes to the vessel wall are apparent. The body tries to compensate for this by ordering the heart to pump harder to maintain normal flow by raising the blood pressure. Superiorly, is the second layer: a subendocardial connective tissue which is continuous with the connective tissue of the myocardium. The endothelial cells ultimately determine the health of your blood vessels and play a … However, research over the last 25 years has shown that the endothelium is an active, multi-functional organ that plays a vital role in metabolic, immunologic, and cardiovascular health.
