elastic fibers. Conducting arteries expand when the ventricles pump blood into them during systole, and recoil during diastole. This lessens the fluctuations in blood pressure exerted on smaller arteries downstream. 2. Distributing (muscular) arteries are smaller branches farther away from the heart that distribute blood to specific organs. You ...
21 Ιουν 2024 · The elastic recoil of the vascular wall helps to maintain the pressure gradient that drives the blood through the arterial system. An elastic artery is also known as a conducting artery, because the large diameter of the lumen gives it a low resistance and enables it to accept a large volume of blood from the heart which is conducted to smaller ...
Elastic arteries include the largest arteries in the body, those closest to the heart, and give rise to the smaller muscular arteries. The pulmonary arteries, the aorta, and its branches together comprise the body’s system of elastic arteries.
1 Αυγ 2018 · Large, elastic arteries are composed of cells and a specialized extracellular matrix that provides reversible elasticity and strength. Elastin is the matrix protein responsible for this reversible elasticity that reduces the workload on the heart and dampens pulsatile flow in distal arteries.
30 Οκτ 2023 · The larger vessels leaving the heart – namely the aorta, pulmonary trunk, common carotid, subclavian, vertebral and common iliac arteries – are elastic arteries. Elastic artery (histological slide) These larger vessels contain two additional layers – the internal and external elastic laminae.
the elastic properties, particularly of large arteries, are impaired in the presence of cardiovascular disease and risk factors such as cigarette smoking, hypertension, diabetes and ageing. Evidence is also emerging that treatment of these risk factors
