question 24

Multiple Choice

How would the body respond to a systemic capillary pressure of 22 mm Hg?

• A) In response to the elevated pressure, fluid would be absorbed from the interstitial spaces to increase blood volume
• B) 22 mm Hg is the normal systemic capillary pressure so no changes in blood volume would occur
• C) In response to the elevated pressure, fluid would leak into the tissue spaces lowering the blood volume
• D) In response to the decreased pressure, fluid would be absorbed from the interstitial spaces to increase blood volume
