WebAs blood enters the systemic capillaries, the blood will lose oxygen and gain carbon dioxide because of the pressure difference of the tissues and blood. In systemic capillaries, P O 2 = 100 mm Hg, but in the tissue cells, P O 2 = 40 mm Hg. This pressure gradient drives the diffusion of oxygen out of the capillaries and into the tissue cells. WebThe oxygen-rich blood then returns to the heart through the veins, which carry oxygenated blood.
