Answer:
Red blood cells
Explanation:
Red blood cells carry the oxygen into the capillaries of the tissues of the body. ... Regarding the partial pressure gradients in systemic capillaries, they have a PaO2 of 100mmHg and a PaCO2 of 40mmHG within the capillary and a PaO2 of 40 mmHg and PaCO2 of 45 mmHg inside issue cells, which allows gas exchange to occur.
