Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Arteries have a thick layer of muscle and elastic tissue.Why is this important?One, some or all answers could be correct?
A
Prevents arteries from bursting due to high blood pressure
B
Smooths out blood flow so it is in pulses
C
Helps to force blood back to the heart
D
Helps the artery to pick up oxygen
Explanation: 

Detailed explanation-1: -The middle layer, the tunica media, is primarily smooth muscle and is usually the thickest layer. It not only provides support for the vessel but also changes vessel diameter to regulate blood flow and blood pressure.

Detailed explanation-2: -Your arteries are thicker and stretchier to be able to handle the higher pressure of blood moving through them. Your veins are thinner and less stretchy. This structure helps veins move higher amounts of blood over a longer time than arteries.

Detailed explanation-3: -Arteries are most elastic and thicker than veins because the blood they receive from the heart enters them with great force and at a much higher pressure than veins so arteries need to be able to withstand the pressure exerted on them.
