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 … WebInternal respiration is gas exchange that occurs at the level of body tissues ( Figure 22.4.3 ). Similar to external respiration, internal respiration also occurs as simple diffusion due to a partial pressure gradient. However, the partial pressure gradients are opposite of those present at the respiratory membrane.
