Consider the arteriolar end of a capillary bed. During capillary exchange, the process of filtration is favored at the arteriolar end due to the higher hydrostatic pressure.

Explanation:

The net filtration pressure at the arteriolar end of the capillary bed is more than 10mmHg. That is why the fluid exits capillary since capillary hydrostatic pressure is 35mmHg that is greater than blood colloidal osmotic pressure which is 25mmHg.

Hence during capillary exchange, the process of filtration is favored at the arteriolar end due to the higher hydrostatic pressure.
