MEDICAL PHYSIOLOGY

Detailed explanation-1: -70-(20 + 30) = 20 mm Hg. Thus, the correct answer is opotion A.

Detailed explanation-2: -Interaction of Hydrostatic and Osmotic Pressures In comparison, the plasma proteins remain suspended in the blood, so the BCOP remains fairly constant at about 25 mm Hg throughout the length of the capillary and considerably below the osmotic pressure in the interstitial fluid.

Detailed explanation-3: -The oncotic pressure exerted by proteins in human plasma has a normal value of approximately 26 to 28 mm Hg.
