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.

Elasticity in Arteries: A similar combination of rubbery and stiff materials creates common mechanical properties in blood vessels of vertebrates and some invertebrates.
18 Σεπ 2019 · In elastic arteries, such as the aorta, the basal lamina is followed by a subendothelial layer composed of connective tissue and smooth muscle cells (Humphrey, 2002; Rhodin, 2014).
To investigate the viscoelasticity of arteries in detail, the dynamic elastic modulus E dyn and the loss elastic modulus ηω need to be calculated considering phase lag Δϕ between diameter and pressure waveform as follows:
2 Φεβ 2018 · We present mouse models of supravalvular aortic stenosis, autosomal dominant cutis laxa-1, and graded elastin amounts that have been invaluable for understanding the role of elastin in arterial mechanics and cardiovascular disease.
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 ...
21 Ιουν 2024 · Distinguish between elastic arteries, muscular arteries, and arterioles on the basis of structure, location, and function; Compare and contrast the three types of capillaries on the basis of structure, location, and function; Describe the basic structure of a capillary bed, from the supplying metarteriole to the venule into which it drains
