Path of a Red Blood Cell. The circulatory system consisting of the heart, arteries, capillaries, and veins, is the pumping mechanism that transports blood throughout the body.In the heart, the left ventricle contracts, pushing red blood cells into the aorta, the body's largest artery.rom here, blood moves through a series of increasingly smaller arteries, until it reaches a capillary, the junction between arteries and veins. Here oxygen molecules detach from the red blood cells and slip across the capillary wall into body tissue.
  Blood passes from the right ventricle to the lungs via the pulmonary artery (the only artery in the body that contains deoxygenated blood veins In the circulatory system â¦ , a vein is a blood vessel that carries blood back toward the heart (as opposed to artery, a blood vessel carrying blood away from the heart).he vena cava (main vein) on the right side carries deoxygenated blood through the right atrium through the right ventricle up into the pulmonary artery, which carries the deoxygenated blood to the lungs to get oxygenated again.
