Blood flow in normal and cancerous tissues. A) In normal tissue, the Pc (capillary hydrostatic pressure) values at the arterial and the venous ends are respectively about 32 mmHg and 15 mmHg (with ΔPc ~18). B) In solid tumors, Pc values at the arterial and the venous ends are respectively about 32 mmHg and 20 mmHg (with ΔPc ~8), which allows development of a gradient at the venous end for the Πi (tissue oncotic pressure) compared to the Pi (interstitium hydrostatic pressure).
