What is the function of thick and elastic walls of large arteries?

Blood vessels have thick elastic muscular walls, especially arteries, because they have to resist the pressures of having blood pumped through them, and they have to undergo vasodilation and vasoconstriction.

∙ 11y agoArteries tend to require thick, strong walls than veins because arterial blood is under much higher pressure than venous blood. This is because arterial blood is experiencing the propelling force of the heart beat and is encountering resistance from the narrow capillaries into which it is ultimately being pumped.

Is especially thick in elastic arteries?
tunica media
What are the three different types of vessels?
arteries thick walled and elastic blood vessels capillaries and veins
What are the different blood vessels?
arteries thick walled and elastic blood vessels capillaries and veins
Do veins have thick elastic walls?
No, arteries have thicker walls because blood pumps through the arteries around the body, therefore blood pumps through arteries which a high pressure so thick walls are needed. Blood goes through veins with a lower pressure as they lead back to the heart to be oxygenated.
A thick walled and elastic vessel that carries nutrients and oxygen away from the heart?
Arteries carry blood containing oygen and nutrients away from the heart. They are thick walled and elastic to cope with the pressure exerted by the contraction of the heart.
Do muscular arteries maintain blood flow during ventricular diastole?
The structure of the various blood vessels is closely related to their function. The vessels which receive blood from the heart, the elastic arteries, have thick, strong walls to cope with the sudden high pressure produced during diastole; they contain abundant elastic material to allow stretch so that the vessel lumen may accommodate the change of volume. They also have a thick, outer coat of collagenous connective tissue whose tensile strength prevents over-distension of the elastic tissue. The elastic recoil of these elastic arteries is responsible for maintaining a continuous, though decreased, flow of blood to smaller vessels during systole.http://ect.downstate.edu/courseware/histomanual/cardiovascular.html
Why does an artery have a large amount of elastic tissue?
Arteries take blood from the heart and transport it to other parts of the body. They have a large amount of elastic tissue because the pressure of the blood flowing through the arteries is high.
What is the thickness of an artery's walls?
It all depends on which one you are comparing, because they come in large ones like the Aorta, down to tiny ones called arterioles. In any case, they are thicker than their corresponding vein.
Why do you think arteries function better with thick walls?
Because they have to deal with high pressure blood
How have arteries adapted to carry blood away from the heart?
The heart pumps the blood out in high pressure so the artery walls are strong and elastic,the walls are thick and contains thick layers of muscle to make them strong , and elastic fibres to allow them to stretch and spring back
Why do arteries function better with thick walls?
Blood vessels that take blood away from the heart are called arteries. The high pressure of the blood pushes strongly on the thick, elastic artery walls. They stretch and shrink as the blood moves through them. This movement of artery walls makes a pulse. When an artery passes close to the skin the pulse can be felt and therefore used to count how fast the heart is beating.
Why must arteries be so thick walled and muscular?
Arteries withstand high pressure during systole (heart contracts), they need thick walls to prevent rupture. In fact larger amounts of elastic tissues than muscle tissues are found as it is constantly stretched and recoiled.
