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 serve to return blood from organs to the heart. In systemic circulation oxygenated blood is pumped by the left ventricle through the arteries to the muscles and organs of the body, where its nutrients and gases are exchanged at capillaries, entering the veins filled with cellular waste and carbon dioxide.
