Question

multiple choice question
which statement accurately describes the development of pressure (which affects water movement) in a capillary network?
o there is a net inward pressure at the venule end.
o the is a net inward pressure at the arteriolar end.
o there is a net outward pressure at the venule end.
o there is no pressure difference at the arteriolar end (inward and outward pressures are balanced)

need help? review these concept resources.

Explanation:

At the arteriolar end of the capillary network, hydrostatic pressure is higher than colloid - osmotic pressure, resulting in a net outward pressure. At the venule end, colloid - osmotic pressure is higher than hydrostatic pressure, leading to a net inward pressure.

Answer:

There is a net inward pressure at the venule end.
