... Diffusion of O2 from Capillaries into Tissues: - O2 is constantly being consumed by cells. Thus PO2 is low in tissues resulting in the influx O2 o Diffusion gradient: PO2 in artery =100 mmHg > PO2 in tissue = 40mmHg O2 flows down its concentration gradient, and results in the delivery of O2 to t ...
