How do you trace a red blood cell from the right pollux capillary bed through the body and return to the right pollux?

Answer 1

To trace a red blood cell from the right pollux capillary bed, it first enters the venules, which merge into the right median cubital vein, then into the brachial vein, and subsequently into the axillary vein. From there, it travels into the subclavian vein, then the brachiocephalic vein, and finally enters the superior vena cava, leading to the right atrium of the heart. The blood cell then moves through the right ventricle into the pulmonary artery, travels to the lungs for oxygenation, and returns via the pulmonary veins to the left atrium. After passing into the left ventricle, it is pumped through the aorta, through the systemic circulation, and eventually reaches the capillary bed of the right pollux again.
