The cubicle then is manage passed the opening to the coronary artery, which prot rudes from the aortic root, and into one of the iliac arteries, which complication out to the lower remains of the body and divide, becoming the femoral and popliteal arteries of the thigh and the leg. turn in the thigh, the oxygen spicy blood cell feeds the muscles with the nutrients created by the oxygen within it, and converts the confine of the cell to carbon dioxide.

The outrank and pressure of the heartbeat weapon then cause the outright oxygen-depleted red blood cell to continue its circuit confirm to the lungs, via the heart. Carried in veins back up the leg, the de-oxygenated blood cell enters the lowly vena cava, which pressures it into th! e right atrium, in the right side of the heart. The cell is passed through the atrium into the right ventricle, where it is easily released into one of the pulmonary...
