Describe the normal pressures or flows at the arterial end of the capillary
a. Electrolytes move from the interstitium into the capillary.
b. Hydrostatic pressure is approximately 24 mm Hg.
c. Osmotic pressure is approximately 30 mm Hg.
d. Plasma minus the proteins flows into the interstitium.
ANS: D
For example, in a typical capillary, blood pressure is approximately 30 mm Hg at the arterial end and approximately 20 mm Hg at the venous end (Figure 12-6). Colloid osmotic pressure of the intravascular fluid remains constant at approximately 25 mm Hg. Hydrostatic pressure along the capillary continually decreases. At the arterial end, hydrostatic pressure normally exceeds osmotic pressure and water flows out of the vascular space into the interstitial space.
