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.
Elasticity describes a material property in which the material returns to its original shape after stress has been applied and then removed. When thinking about elasticity, think about a coiled metal spring or a rubber band. Imagine applying stress to a rubber band by pulling on it.
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.
31 Ιαν 2024 · Worked example: Blood vessel features. The correct answer is B. This is because elastic arteries do not contain many smooth muscle fibres and are not able to perform vasoconstriction or vasodilation. In contrast, muscular arteries contain much more smooth muscle.
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
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.
