Consider the arteriolar end of a capillary bed. During capillary exchange, the process of __________ is favored at the arteriola
krok68 [10]

Answer:

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

Explanation:

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

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