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.
1 Φεβ 2002 · A simplified model of arterial elasticity has been used in many studies in which measurements are confined to the circumferential direction, and elastic non‐linearity is treated by defining incremental elastic properties over a limited region of the stress strain curve that is taken to be linear (for instance, that corresponding to the part ...
26 Δεκ 2019 · These arteries progressively lose their low-stretch bearing component, shifting load to stiffer matrix components (collagen). At the same time, arteries also lose some of their longitudinal elasticity and geometry, leading to elongation and increased tortuosity.
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 2022 · Elasticity of arteries is a fundamental structural property that is a major determinant of the relationship of the pulsatile components of arterial blood pressure and flow.
20 Δεκ 2021 · In this paper, we present a localised method for incorporating the effects of elastic walls into blood flow simulations using the lattice Boltzmann method implemented by the open-source code...
