Question

In general it is expected that ________. A) hydrostatic pressure will rise as blood moves away from the arteriole end of the capillary bed B) hydrostatic pressure will drop as blood moves away from the arteriole end of the capillary bed C) hydrostatic pressure will remain constant throughout the capillary bed D) osmotic pressure will be lower in the arteriole end of the capillary bed compared to the venous end

Answer 1

Hydrostatic pressure will drop as blood moves away from the arteriole end of the capillary bed.

Step-by-step explanation:

As fluid exits a capillary and moves into tissues, the hydrostatic pressure in the interstitial fluid correspondingly rises. This opposing hydrostatic pressure is called the interstitial fluid hydrostatic pressure (IFHP). Generally, the CHP originating from the arterial pathways is considerably higher than the IFHP, because lymphatic vessels are continually absorbing excess fluid from the tissues. Thus, fluid generally moves out of the capillary and into the interstitial fluid. This process is called filtration.

Answer 2

A) hydrostatic pressure will rise as blood moves away from the arteriole end of the capillary bed
