A) Most fluid that leaves the arterial end of a capillary reenters the venous end of a capillary.
B) Interstitial fluid normally has a higher osmotic pressure than plasma.
C) Constriction of the precapillary sphincter will increase blood pressure in the capillary.
D) Interstitial protein concentration is normally higher than plasma protein concentration.
E) Most fluid that leaves the arterial end of a capillary enters the lymphatic system.
Capillary Exchange
The process by which nutrients, gases, and wastes are exchanged between blood and tissues through capillary walls.
Precapillary Sphincter
A ring-like muscle at the entrance of capillaries that regulates blood flow into the capillary.

Final Answer :
A
Explanation :
Most of the fluid that exits the capillaries at the arterial end due to hydrostatic pressure is reabsorbed at the venous end due to osmotic pressure, primarily driven by plasma proteins.
