Since the reduced diastolic recoil ensures diastolic pressure from being elevated the entity is aptly named as isolated systolic hypertension. 1 Answer. With inhalation, the intrapleural pressure (the pressure within the pleural cavity) of the lungs decreases. Each tissue in the body contains cells of different types that are specialised to suit their function. Elastic arteries contain larger numbers of collagen and elastin filaments in their tunica media than muscular arteries do, giving them the ability to stretch in response to each pulse. Rishi is a pediatric infectious disease physician and works at Khan Academy. In rodent lung, elastic arteries are large arteries with a medial layer consisting of alternating layers of concentric elastic lamina and smooth muscle cells. This proves that the arteries have more collagen in the muscle walls which allows them to stretch and recoil. A sensitive indicator of elastic recoil (ER) is the coefficient of retraction—the ratio of the maximal static recoil pressure to total lung capacity. Elastic arteries are the largest arteries in the body, example of this is the aorta. Elastic arteries refer to an artery with a large number of collagen and elastin filaments in the tunica media, which gives it the ability to stretch in response to each pulse, while muscular arteries refer to a medium-sized artery that draws blood from an elastic artery and branch into “resistance vessels” including small arteries and arterioles. 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 … Elastic arteries include the largest arteries in the body, those closest to the heart, and give rise to the smaller muscular arteries. Learn the differences between an artery and a vein.
