A fundamental question about the morphogenesis of blood vessels, for which we still have no clear answer, is what mechanisms act to terminate the iterative layering process that drives formation of the tunica media?

The adventitia, (advɛnˈtɪʃə) is the outer layer of fibrous connective tissue surrounding an organ. The outer layer of connective tissue that surrounds an artery, or vein - the tunica externa, is also called the tunica adventitia The tunica externa (New Latin outer coat) — also known as the tunica adventitia (New Latin additional coat), 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 The adventitia is the outermost layer and is a thin layer of loose connective tissue. In places, a thin layer of simple squamous epithelium called mesothelium covers adventitia on the external surface. When covered by mesothelium, the adventitia is called the serosa.

Summary. Blood vessels are an integral component of the circulatory system.The five types of blood vessels are (in order of circulation): arteries, arterioles, capillaries, venules, and veins.The primary function of large blood vessels (i.e., arteries and veins) is the transport of blood to and from the heart, whereas smaller blood vessels (e.g., capillaries) enable substance exchange between. Veins (V) are much thinner-walled. The intima and media are separated by the internal elastic lamina (IEL), and the tunica media and adventitia are separated by the external elastic lamina (EEL).

There may also be an associated pericyte within the basal lamina of the endothelial. The basal lamina is unusually thick in the trachea, and appears here as a faintly stained layer of cartilage which helps to keep the lumen of the trachea from collapsing and beyond that is connective tissue of the adventitia that blends with tissue of the mediastinum.

Both the lamina propria and adventitia were significantly thicker in COPD subjects, with the lamina propria showing at least a 10-fold change overall compared to normal controls, whereas in the adventitial areas there was a two- to three-fold thickening Other articles where Tunica adventitia is discussed: artery: The outermost coat, or tunica adventitia, is a tough layer consisting mainly of collagen fibres that act as a supportive element. The large arteries differ structurally from the medium-sized arteries in that they have a much thicker tunica media and a somewhat thicker tunica adventitia Endothelium rests on a internal elastic lamina, which may also be incomplete. The tunica media consists of 1-3 concentric layers of smooth muscle cells.

Combining these information with advanced diagnostic endoscopy, the esophagus is organized, from the luminal side to outside, into five layers (epithelium, lamina propria with lamina muscularis mucosa, submucosa, muscle layer, adventitia) There is sometimes a condensation of elastic fibers in the outer portion of the media that may be an external elastic lamina, which varies from artery to artery.

The outside layer is either serosa or adventitia, depending on location--see your textbook for an explanation.
