Question

question 52 1.67 pts which statement accurately compares filtration and reabsorption? the direction of filtration can be either into or out of the blood, but reabsorption always involves fluids entering the blood. filtration involves bulk flow of fluid out of the blood, whereas reabsorption is bulk flow back into the blood. filtration is driven by concentration gradients, whereas reabsorption depends on hydrostatic pressure. filtration happens at the venule end of a capillary bed and reabsorption happens in feeder arterioles.

Explanation:

Filtration is the movement of fluid out of the blood (bulk - flow) due to hydrostatic pressure, typically at the arteriole end of a capillary bed. Reabsorption is the movement of fluid back into the blood (bulk - flow), mainly at the venule end of a capillary bed. It is driven by osmotic pressure.

Answer:

B. Filtration involves bulk flow of fluid out of the blood, whereas reabsorption is bulk flow back into the blood.
