Endothelium Endothelium is a type of epithelium that lines the interior surface of blood vessels and lymphatic vessels, forming an interface between circulating blood or lymph in the lumen and the rest of the vessel wall. It is a thin layer of simple squamous cells called endothelial cells.Endothelial cells in direct contact with blood are called vascular endothelial cells, whereas those in direct contact with lymph are known as lymphatic endothelial cells.Vascular endothelial cells line the entire circulatory system, from the heart to the smallest capillaries.ndothelial cells in direct contact with blood are called vascular endothelial cells, whereas those in direct contact with lymph are known as lymphatic endothelial cells.

Tunica intima Tunica intima. The tunica intima (New Latin inner coat), or intima for short, is the innermost tunica (layer) of an artery or vein. It is made up of one layer of endothelial cells and is supported by an internal elastic lamina. The endothelial cells are in direct contact with the blood flow. The tunicae of blood vessels are three layers—an inner layer (the tunica intima), a middle layer (the tunica media), and an outer layer (the tunica adventitia). In dissection, the inner coat (tunica intima) can be separated from the middle (tunica media) by a little maceration, or it may be stripped off in small pieces; but, because of its friability, it cannot be separated as a complete membrane.

Tunica externa Tunica externa. The tunica externa (New Latin outer coat), also known as the tunica adventitia (New Latin additional coat)(or adventitia for short), is the outermost tunica (layer) of a blood vessel, surrounding the tunica media. It is mainly composed of collagen and, in arteries, is supported by external elastic lamina.

Picture of the Arteries The intima, the inner layer lined by a smooth tissue called endothelium; The media, a layer of muscle that lets arteries handle the high pressures from the heart; The adventitia, connective tissue anchoring arteries to nearby tissues; The largest artery is the aorta, the main high-pressure pipeline connected to the heart's left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries' smaller branches are called arterioles and capillaries.

What type of blood vessel enables the exchange of nutrients and gas between the blood and cells of the body? In vessels larger than 1 mm in diameter a subendothelial layer of loose connective tissue (a basement membrane) supports the endothelium---- ---The tunica media is the middle layer and consists circularly arranged smooth muscle cells and sheets of elastin.) Three distinct layers or tunics form the walls of blood vessels: ---The tunica interna (tunica intima) is the innermost layer. It contains the endothelium which is a continuation of the endocardial lining of the heart.

Structure and Function of Blood Vessels The tunica intima (also called the tunica interna) is composed of epithelial and connective tissue layers. Lining the tunica intima is the specialized simple squamous epithelium called the endothelium, which is continuous throughout the entire vascular system, including the lining of the chambers of the heart.

It is a thin wall lines that lines the artery wall with endothelial cells successfully separating blood flow from other layers of the wall of artery. The media is the middle and the thickest of the three walls (Wright, 1993).Media contain strength mechanism like smooth muscles, elastin, and collagen.

Blood Vessel Structure and Function Arteries and veins are composed of three tissue layers. The thick outermost layer of a vessel (tunica adventitia or tunica externa ) is made of connective tissue. The middle layer ( tunica media ) is thicker and contains more contractile tissue in arteries than in veins. It consists of circularly arranged elastic fibers, connective tissue, and smooth muscle cells. The inner layer ( tunica intima ) is the thinnest layer, comprised of a single layer of endothelium supported by a subendothelial layer.
