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.
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.
2 Φεβ 2018 · In this review, we summarize the biochemistry of elastin and elastic fiber assembly process. We discuss measures of passive arterial mechanics that are affected by elastin amounts, elastic fiber integrity, and cross-linking.
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.
1 Μαρ 2023 · Elastic arteries like your aorta and pulmonary artery are arteries that carry a large amount of blood away from your heart. Their high elastic content lets them handle the force of blood coming from your heart nearby.
