Learning Objectives. Distinguish the elastic artery from the muscular artery. Key Points. Elastic arteries include the largest arteries in the body, those closest to the heart. They give rise to medium-sized vessels known as muscular, or distributing, arteries.
30 Οκτ 2023 · In this worksheet we’ll be focusing on the arteries of the cardiovascular system, but you can test your knowledge of the veins and organs using our interactive cardiovascular system quizzes further down the page.
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 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.
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).
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.
