Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During pressure filtration, ____ pressure forces plasma out of capillaries into surrounding cells where it is known as ____
A
Low/tissue fluid
B
High/tissue fluid
C
Low/lymph
D
High/lymph
Explanation: 

Detailed explanation-1: -CHP is the force that drives fluid out of capillaries and into the tissues. 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).

Detailed explanation-2: -Capillary Hydrostatic Pressure (PC) This pressure drives fluid out of the capillary (i.e., filtration), and is highest at the arteriolar end of the capillary and lowest at the venular end.

Detailed explanation-3: -Under normal conditions, the balance of forces acting across the microvascular walls of exchange vessels favors the net flux of fluid from the bloodstream to the interstitium, a process commonly referred to as capillary filtration.
