An elastic artery (conducting artery or conduit artery) is an artery with many collagen and elastin filaments in the tunica media, which gives it the ability to stretch in response to each pulse. [1] This elasticity also gives rise to the Windkessel effect , which helps to maintain a relatively constant pressure in the arteries despite the ...
Degenerative changes that occur with age in the walls of large elastic arteries are thought to contribute to increased stiffening over time, including the disruption of lamellar elastin structures within the wall, possibly due to repeated cycles of mechanical stress; inflammation; [7] changes in arterial collagen proteins, partially as a ...
It is mainly composed of collagen and, in arteries, is supported by external elastic lamina. The collagen serves to anchor the blood vessel to nearby organs, giving it stability. The three layers of the blood vessels are: an inner tunica intima, a middle tunica media, and an outer tunica externa.
Vasa vasorum are networks of small blood vessels that supply the walls of large blood vessels, such as elastic arteries (e.g., the aorta) and large veins (e.g., the venae cavae). The name derives from Latin 'the vessels of the vessels'.
There are various kinds of blood vessels: [14] Arteries. Elastic arteries; Distributing arteries; Arterioles; Capillaries (smallest type of blood vessels) Venules; Veins. Large collecting vessels, such as the subclavian vein, the jugular vein, the renal vein and the iliac vein. Venae cavae (the two largest veins, carry blood into the heart ...
Systemic arteries can be subdivided into two types—muscular and elastic—according to the relative compositions of elastic and muscle tissue in their tunica media as well as their size and the makeup of the internal and external elastic lamina. The larger arteries (>10 mm diameter) are generally elastic and the smaller ones (0.1–10 mm ...
This inflammation disrupts the elastic fibers in the privates, causing hardened plaques, or scar tissue, to form on the privates in genetically predisposed individuals. ... tissues, blood vessels ...
The Windkessel analogy illustrated. Windkessel effect (German: Windkesseleffekt) is a term used in medicine to account for the shape of the arterial blood pressure waveform in terms of the interaction between the stroke volume and the compliance of the aorta and large elastic arteries (Windkessel vessels) and the resistance of the smaller arteries and arterioles.
