C)facilitated diffusion
D)Brownian movement

Question

Quizplus · Accepted Answer

The major filtration force in capillaries is hydrostatic pressure, which is the pressure exerted by the fluid in the capillaries against the wall of the capillaries. This pressure is generated by the pumping action of the heart and is typically higher at the arterial (inlet) than the venous (outlet) end of the capillary bed, thus driving the movement of fluids and substances out of the capillaries and into tissues.
