Elastic Arteries. Elastic arteries are the largest arteries near the heart—the aorta and its major branches—with diameters ranging from 2.5 cm (about the width of the thumb) to 1 cm (slightly less than the width of the little finger). Their large lumen allows them to serve as low-resistance conduits for conducting blood between the heart Arteries. Usually carry Thick walls (with muscle and elastic fibres) to withstand high pressure. Muscle and elastic fibres within the walls also allow the artery to expand and recoil with each 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 within specific regions of the body.

18 In younger adults, recoil in the elastic central arteries transmits a portion of each stroke volume in systole and a portion of each stroke volume in diastole, as illustrated in Figure 14-2, A. 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. Between heart contractions, the elastic walls recoil, to maintain blood pressure, continuing to move blood even when ventricles are relaxed.

Muscular arteries are smaller compared to elastic arteries. The examples are coronary artery and femoral artery. Structural Changes Elastic arteries can stretch and recoil again in response to the pressure. Muscular arteries can constrict and relax which change This fully-resourced lesson explores how the structure of arteries, veins and capillaries relates to their functions.

3. aorta and arteries expand and store pressure in elastic walls.

Elastic recoil of the arteries maintains diastolic blood pressure, and helps in the opposition of the aortic and pulmonary cusps during diastole.

Additionally, the elastic recoil helps conserve the energy from the pumping heart and smooth the flow of blood around the body through the Windkessel effect. In elastic arteies the tunica media is very rich with elastic and connective tissue. 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.

In other words, some of the  continuous because the upstream arterial tree acts as an elastic.

It is worth to note that in that   5 Mar 2018 Pressure: The pressure in the arteries is greater than that in the veins. Arterial wall recoils due to presence of elastic fibers, and this recoil is  elastic recoil the ability of a stretched elastic object or organ, such as the lung or bladder, to return to its resting position.
