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 ...
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.
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 ).
1 Μαρ 2021 · Elasticity in Arteries: a similar combination of rubbery and stiff materials creates common mechanical properties in blood vessels of vertebrates and some invertebrates
1 Σεπ 2015 · Elastic arteries have a relativ ely large diameter and ar e closer to the heart (e.g., aorta or carotid artery); their media contains a lot of elastic membranes. The number of elastic...
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.
