In rodent lung, elastic arteries are large arteries with a medial layer consisting of alternating layers of concentric elastic lamina and smooth muscle cells. There is a gradual transition from elastic arteries to the smaller muscular arteries, in contrast to other species, in which branching of the arteries is associated with abrupt changes in wall thickness or lumen size. Anonymous. The artery walls contain collagen and elastic tissues which allow it to stretch and recoil, where as the veins do not have as much connective tissue containing collagen fibres. The elastic recoil of the vascular wall helps to maintain the pressure gradient that drives the blood through the arterial system. Purpose: Elastic recoil of the arterial wall has been shown to be responsible for a significant loss of luminal area after balloon angioplasty in the coronary arteries, but it has not been well studied in the peripheral arteries. Find out more about how we use your information in our Privacy Policy and Cookie Policy. 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.

Lung elastic recoil is an important physiologic characteristic of the lungs, which may change in qualitatively different ways in various diseases. Answer Save. Conversely, in almost all forms of airflow obstruction, elastic recoil is decreased. You can explore tissues using microscopy, and by looking at the overall properties of suitable samples. A fenestrated external elastic lamina is present; it allow diffusion of nutrient from the adventitia to the media. my textbook says it decreases pressure but shouldn't it increase since there i. Since the reduced diastolic recoil ensures diastolic pressure from being elevated the entity is aptly named as isolated systolic hypertension. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. (b) The elastic recoil of arteries during cardiac ⿞ diastole continues driving the blood forward when the heart is not pumping. A sensitive indicator of elastic recoil (ER) is the coefficient of retraction—the ratio of the maximal static recoil pressure to total lung capacity. Hence there could be a mild fall in diastolic pressure with physiological aging when recoil is attenuated . inferior vena cava. This is not a problem as the arteries, being closer to the heart, have to withstand a much higher pressure than the veins do. See how arteries behave like sling shots, shooting blood (not rocks) onwards! Another way to prevent getting this page in the future is to use Privacy Pass.
