What else can I help you with?
Are coronary arteries elastic?
Yes, arteries have elastic lamina.
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.
Does tunica media of elastic arteries contains more elastic fibers than muscular arteries?
true
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
Which blood vessels have elastic fibers?
Arteries contain elastic fibres. These are particularly abundant in the large conducting arteries, such as the aorta.
Which tunic is especially thick in elastic arteries?
Arterial walls are made up of three layers: the tunica intima, tunica media, and tunica externa. The tunica media is the thickest layer in arteries.
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

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.
The arterioles muscular arteries and elastic arteries are in what position from heart to capillaries?
left ventricle --> elastic arteries (aorta and its larger branches)--> Muscular arteries --> arterioles --> capillaries
Does tunica media of elastic arteries contains more elastic fibers than muscular arteries?
true
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.

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.
