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 - Free download as Word Doc (.doc), PDF File (.pdf), Text File (.txt) or read online for free. Your body's largest artery, the aorta, and its main branches constitute the "elastic arteries" When the left ventricle pumps blood into these arteries, they expand or swell.
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.
Keywords: Arteries; Mechanical properties elasticity 1. Introduction It is well known that the elasticity of materials is expressed in Hooke’s law as follows: Tensile stress of a solid is proportional to the amount of deformation, provided the deformation is not permanent. Hooke’s law applied to an elastic bar of length l can be expressed ...
26 Δεκ 2019 · Top, the typical nonlinear relation between luminal pressure and area in large elastic arteries, explained by the progressive shift in load bearing from elastin to collagen fibers. Data translate into distensibility and pulse wave velocity (PWV) with the use of the Bramwell-Hill relation.
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.
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 enables it to accept a large volume of blood from the heart and conduct it to smaller branches.
