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.
4 Μαΐ 2021 · An arterial wall has both elastic and viscous characteristics, and pathological and degenerative changes in the wall tissue affect the viscoelastic behavior of the artery wall. The arterial viscoelasticity may provide useful information regarding the development and progression of arterial diseases.
18 Σεπ 2019 · Schematic drawing of a healthy elastic artery. Stress-free (B 0 ), unloaded (B * ) and deformed (B) configuration of an arterial segment. The coordinate triplets (ρ, φ, ξ), (R, Θ, L) and (r, θ,...
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
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.
Elasticity in Arteries: A similar combination of rubbery and stiff materials creates common mechanical properties in blood vessels of vertebrates and some invertebrates.
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 ...
