Elasticity in Arteries: A similar combination of rubbery and stiff materials creates common mechanical properties in blood vessels of vertebrates and some invertebrates.
The elastic arteries are large arteries close to the heart such as the aorta and the carotid arteries and are abundant in elastin. Their media is made of concentric layers whose unit is called a lamellar unit [ 1 ], a pair of elastic lamina mainly made of elastin and a smooth muscle-rich layer (Fig. 4.1 ).
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.
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,...
21 Σεπ 2016 · We begin with a brief, general discussion of measurement and modeling of cardiovascular tissue viscoelasticity. We then review known viscoelastic behavior of arteries, veins, capillaries, blood...
1 Ιαν 2010 · Structural changes in the large conduit arteries decrease their elasticity and increase stiffness. Risk factors and effective preventive therapy alter prognosis by functional and structural effects on the arteries. A focus on arterial elasticity can improve the diagnostic and therapeutic approach to cardiovascular disease
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 ...
