Give a precapillary arteriolar pressure of 46 mmHg, a postcapillary venule pressure of 16 mmHg, an intersitial fluid hydrostatic pressure of 1 mmHg, and a plasma oncotic (osmotic) pressure of 25 mmHg, what is the average net pressure of this capillary?

Answer:

ΔP = 4 mmHg

Step-by-step explanation:

Pressure is a scalar quantity so it is additive

Capillary pressure from arterial to venous blood transfer is pressure

ΔP = P_arterial - P_venosa - P_interticial - P_osmotica

ΔP = 46 -16 -1 -25

ΔP = 4 mmHg

This is the pressure that carries blood from the arteries to the veins
