in capillary beds, the net inward pressure at the venular ends of the capillaries is less than the net outward pressure at the arteriolar ends of the capillaries. what is the result of this difference in pressures?
pressure in the venules increases.
lymphatic vessels push fluid into the capillaries.
more fluid leaves the capillaries than returns.
more fluid flows into the capillaries than moves out.

Explanation:

When the net inward pressure at the venular ends of capillaries is less than the net outward pressure at the arteriolar ends, the balance of fluid movement favors fluid leaving the capillaries over returning. This is due to the pressure - gradient driving fluid outwards being stronger than the one drawing it inwards at the relevant capillary ends.

Answer:

More fluid leaves the capillaries than returns.
