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.
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.
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 enables it to accept a large volume of blood from the heart and conduct it to smaller branches.
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).
30 Οκτ 2023 · Blood vessels of the body. The vessels of the body include arteries, arterioles, capillaries, venules and veins. This is in fact the order in which blood circulation occurs. Arteries and veins contain three layers: Tunica externa (outer layer) - comprised of elastic and collagen fibres.
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.
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 ...
