Tunica media consists of many fenestrated lamella of elastin. Ask a question. The elastic fibres allow the arteries to dilate and constrict. my textbook says it decreases pressure but shouldn't it increase since there i. blood pressure is normally measured in the. • inferior vena cava. Distributing arteries are medium-sized arteries that draw blood from an elastic artery and branch into resistance vessels. Each tissue in the body contains cells of different types that are specialised to suit their function. The implantation of a balloon-expandable Palmaz-Schatz stent was performed in one iliac artery and a balloon angioplasty alone was performed in the contralateral artery (n = 34 arteries). The elastic recoil of the vascular wall helps to maintain the pressure gradient that drives the blood through the arterial system. The blood that enters the elastic arteries after the heart contracts causes the vessel to stretch. Aortic aneurysm anterior • Aneurysms happen due to changes in the tunica ⿞ … The elastic fibres allow the blood vessels to expand andcontract to adopt to the blood flow as well as regulate the bloodflow changes 2 .The functions of the arteries to take oxygenated blood from the heartto the rest of the body 3 .Veins on the other hand take … This proves that the arteries have more collagen in the muscle walls which allows them to stretch and recoil. The pulmonary arteries, the aorta, and its branches together comprise the body's system of elastic arteries. Elastic fibers provide recoil which is what you need in arteries to propel the blood forward. A fenestrated external elastic lamina is present; it allow diffusion of nutrient from the adventitia to the media. In rodent lung, elastic arteries are large arteries with a medial layer consisting of alternating layers of concentric elastic lamina and smooth muscle cells. 1 decade ago.
