Water and dissolved substances leave the arteriole end of a capillary due to ________, and enter the venule end of a capillary due to ________.
A)hydrostatic pressure being higher than osmotic pressure; active transport being greater than osmotic pressure
B)osmotic pressure being higher than hydrostatic pressure; hydrostatic pressure being higher than osmotic pressure
C)hydrostatic pressure being higher than osmotic pressure; osmotic pressure being higher than hydrostatic pressure
D)osmosis; active transport

Question

Quizplus · Accepted Answer

Hydrostatic pressure in the capillary is greater than osmotic pressure, resulting in the outward movement of water and dissolved substances at the arteriole end. At the venule end, osmotic pressure is greater than hydrostatic pressure, causing water and dissolved substances to move back into the capillary.
