       A. Hyperproteinemia                    

   B. A ureteral stone

      C. Dilation of the afferent arteriole         

   D. Dilation of the efferent arteriole

      E. Constriction of the efferent arteriole

     3.  Glucose reabsorption occurs in the

        B. loop of Henle           

        C. distal tubule

4.   Regarding the renal circulation

a) The kidneys receive about 10% of the resting cardiac output

b) As cardiac output increases during exercise renal blood flow rises

c) Renal blood flow is maintained within narrow limits despite changes in arterial blood pressure

   d) Increased activity in the renal sympathetic nerves results in increased blood flow to the kidneys.
