|
Fluids would be likely to leave or filter out of the capillary if ____
|
|
net hydrostatic pressure (HP) is greater than net osmotic pressure (OP)
|
|
|
net hydrostatic pressure (HP) is less than net osmotic pressure (OP)
|
|
|
net filtration pressure (NFP) is negative
|
|
|
osmotic pressure (OP) in the capillary is high
|
Explanation:
Detailed explanation-1: -Osmotic pressure remains relatively constant over the length of the capillary, but hydrostatic pressure drops sharply as it nears the venule end due to the initial loss of fluid volume. At that point, the interstitial osmotic pressure becomes stronger than the capillary’s hydrostatic pressure.
Detailed explanation-2: -Net filtration occurs near the arterial end of the capillary since capillary hydrostatic pressure (CHP) is greater than blood colloidal osmotic pressure (BCOP).
