WebJun 8, 2024 · As blood enters the systemic capillaries, the blood will lose oxygen and gain carbon dioxide because of the pressure difference between the tissues and blood. In systemic capillaries, PO 2 =100mmHg, but in the tissue cells, PO 2 =40mmHg. This pressure gradient drives the diffusion of oxygen out of the capillaries and into the tissue … WebThe respiratory system transports oxygen from the air we breathe, through a system of tubes, into our lungs and then diffuses it into the bloodstream, whilst carbon dioxide …
