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
ARTERIES Blood vessels that carry blood away from the heart are called arteries. They are the thickest blood vessels and they carry blood high in oxygen known as oxygenated blood (oxygen rich blood).
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.
26 Δεκ 2019 · Figure 1. 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.
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.
30 Οκτ 2023 · The larger vessels leaving the heart – namely the aorta, pulmonary trunk, common carotid, subclavian, vertebral and common iliac arteries – are elastic arteries. Elastic artery (histological slide) These larger vessels contain two additional layers – the internal and external elastic laminae.
21-1 Blood Vessels. The Tunica Intima (Inner Layer) Includes: The endothelial lining. Connective tissue layer. Internal elastic membrane. In arteries, is a layer of elastic fibers in outer margin of tunica intima.
