arteries have thick walls that are both strong and flexible.
when your ventricles contract,blood surges through your
arteries,causing their elastic walls to expand and then relax!!! :)

∙ 14y agoThe structure of veins is similar to that of arteries, again consisiting of three layers:
- Tunica Adventitia: This is the strong outer covering of arteries and veins which consists of connective tissues, collagen and elastic fibres.
- Tunica Media: This is the middle layer and consists of smooth muscle and elastic fibres. This layer is thinner in veins.
- Tunica Intima: This is the inner layer which is in direct contact with the blood flowing through the vein. It consists of smooth endothelial cells. The hollow centre through which blood flows is called the lumen. Veins also contain valves which prevent the back flow of blood and aid venous return.

∙ 12y agoAlright, ateries are the vessles that trake blood from the heart to other areas of the body to provide nutrients and oxygen. They only carry blood rich in oxygen except for the pulmonary artery which takes blood to the lungs to get oxygen. they have more smooth muscles and are "stronger" to help the flow of blood.
