You panic. You feel hurt and stupid at the same time. About 2 days later you feel a lot better and actually free from the burden of carrying around all that weight. You think, 'at least I know now how they feel'. Then you pick yourself up, dust yourself off and move on. Love is sweet.
The cardiovascular system contains your arteries. This system is responsible for pumping blood throughout the body and contains the heart, veins, capillaries, and other parts â¦that pump blood to the rest of the body. Blood passes through arteries, therefore making the arteries part of the cardiovascular system.
Veins have the same three layers as arteries and are elastic, but they have a less-muscular middle layer, making their walls thinner. Also, unlike arteries, some veins have valves (tissue flaps) that permit blood to flow in only one direction, back to the heart.rteries carry blood away from the heart; capillaries reach all of the body's seventy trillion cells; and veins carry blood back to the heart. Because blood vessels form a circular route, this system is also called the circulatory system.
