Constriction of efferent aeriolar produces:: (A) Biphasic response on GFR, (B) Increased per-tubular oncotic pressure, (C) Increased per-tubular absorption, (D) All
Answer is D. Constriction of efferent aeriolar produces: Increased per-tubular oncotic pressure Decreased hydrostatic pressure Increased reabsorption of water In less than 3 fold increase in resistance GFR increases In more than 3 fold increase in resistance GFR decrease Ref:Guyton and Hall textbook of medical physiology 12th edition,page number:471-474
