Page ID. An elastic or conducting artery has a large number of collagen and elastin filaments in the tunica media. 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.
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 ...
Elastic recoil in arteries and veins. Take rings of artery and vein tissue. Load and unload with 10 g masses and hence assess differences in elasticity. Consider how the elastic properties suit the different functions of artery and vein in the circulatory system.
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.
1. What are identifying features of elastic arteries? Multiple sheets of elastic lamellae in the wall. 2. With increased age and increased blood pressure, a layer in elastic arteries increase in thickness. Name the layer and the component in the layer which cause the increased thickness.
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.
