- The tunica adventitia is the outermost layer of the arteries and veins. The word 'adventitia' in tunica adventitia comes from the Latin 'adventicius,' which means 'coming from outside.' This strong outer layer is composed of connective tissue that allows the blood vessel to withstand forces acting on the vessel wall.ll arteries and veins contain three layers. The innermost layer is called the tunica intima. The muscular middle layer is called the tunica media, and the outermost layer is called the tunica adventitia.

Blood Vessels Veins: It carries blood from the capillaries back towards the heart. They have much slighter walls compared to arteries. Sinusoids: They are very small vessels located within the bone marrow, liver and spleen. Layers of Blood Vessels. Both arteries and veins consist of three layers. Tunica Intima: It is one of the innermost and thinnest layers of arteries and veins. It comprises of endothelial cells. They are in direct contact with the flow of blood. It intern consists of three layers. I.e. Inner Layer, Middle Layer, and Outer Layer.

Histology of blood vessels The walls of arteries and veins are composed of endothelial cells, smooth muscle cells and extracellular matrix (including collagen and elastin). These are arranged into three concentric layers: intima, media and adventitia. The intima is the inner layer abutting the vessel lumen.

- Ordinary fibrous connective tissue forms the outer layer of blood vessels. This adventitial connective tissue is usually more or less continuous with the stromal connective tissue of the organ in which the vessel is found. That is, there is not distinct outer boundary to the tunica adventitia.

-   The Endothelium   The Endothelium is a single layer of cells which line the internal wall of blood vessels. It enables the blood to flow smoothly inside the blood … vessels. In the past it was considered to be just a Teflon like coating.

Blood vessel 1 Tunica adventitia : (the thickest layer in veins) entirely made of connective tissue. 2  It also contains nerves that supply the vessel as well as nutrient capillaries (vasa vasorum) in the larger blood vessels.here are three major types of blood vessels: the arteries, which carry the blood away from the heart; the capillaries, which enable the actual exchange of water and chemicals between the blood and the tissues; and the veins, which carry blood from the capillaries back toward the heart.

What are the Three layers of arteries? What are the Three layers of arteries?   The tunica intima is the innermost layer containing mostly endothelium, the one through which the lumen runs. Surrounding this is tunica media which mostly muscle tissue…. And finally surrounding this is the outermost layer, the tunica adventitia which is mostly connective tissue.

Ultrastructure of Blood Vessels ARTERIOLES. In arterioles, the tunica intima consists of a continuous endothelium and a very thin subendothelial layer. In addition, a thin, fenestrated internal elastic lamina is present in larger arterioles but absent in terminal arterioles. Generally, the tunica media consists of 2 layers of smooth muscle cells.

Cardiovascular System The wall of the heart is composed of three distinct layers. 2. The outermost layer, the epicardium, is made up of connective tissue and epithelium, and houses blood and lymph capillaries along with coronary arteries. 3. The middle myocardium consists of cardiac muscle and is the thickest layer of the heart wall. 4. The inner endocardium is smooth and is made up of connective tissue and epithelium, and is continuous with the endothelium of major vessels joining the heart. a. The endocardium houses Purkinje fibers.

Basic Structure of a Blood Vessel The three structural layers of a generalized blood vessel from innermost to outermost are the tunica intima, tunica media and tunica adventitia.Modification of this basic design account for the five types of blood vessels and the structural and functional differences among the various vessel types.The tunica intima forms the inner lining of blood vessel and direct contact with the blood as it flows through the lumen of the vessel.he tunica interna (intima) forms the inner lining of a blood vessel and is in direct contact with the blood as it flows through the lumen, or interior opening, of the vessel.

Blood Vessel Tunics The innermost layer of a blood vessel wall is the tunica intima (too'ni-ka in-ti'ma; intimus = inmost), or tunica interna. It is composed of an endothelium (a simple squamous epithelium lining the blood vessel lumen) and a subendothelial layer made up of a thin layer of areolar connective tissue. The tunica media (me'de-a; medius = middle) is the middle layer of the vessel wall. It is composed of circularly arranged layers of smooth muscle cells. Sympathetic innervation causes the smooth muscle to contract, resulting in vasoconstriction (va'so-kon-strik'shun), or narrowing of the blood vessel lumen.

artery Structurally, a typical artery has three tissue layers: the inner layer (tunica intima) has endothelial tissue; the middle layer (tunica media) has smooth muscle and elastic connective tissue; and the outer layer (tunica externa) has connective tissue.

- Tunica intima. This is the innermost layer and lines the lumen of the blood vessels. It consists of simple squamous epithelium and a thin layer of areolar CT (basement membrane) to stick it to the Tunica media.. The basement membrane is often seen as a squiggly line right under the simple squamous epithelium.

Human Physiology/Print Version This is the underlying layer of areolar connective tissue. It contains blood vessels, nerve endings, lymphatic vessels, and cells of the immune system. It provides mechanical and metabolic support for the epithelium and protection as part of the immune system.he outer boundary of the mucosa is often marked by a band of smooth muscle arranged in two thin concentric layers, an inner circular layer and outer longitudinal layer. Contraction of the muscularis mucosae agitates the epithelium and alters its shape.

Blood Vessels: Arteries, Capillaries & More Only the microscopic capillaries serve as the location for the exchange of gases and nutrients between blood and tissue cells. The capillary walls are very thin and composed of a single layer of endothelial cells, which are very thin flattened cells that line the inner walls of all of the blood vessels.

- THE HEART. three tissue layers (outside to inside): 1) The epicardium, the outermost layer, consists of an outer layer of mesothelial cells (simple. squamous) overlying connective tissue (DIACT and adipose tissue). Nerves that innervate the. heart run in this layer, as well as the coronary arteries.
