Question

3) An increase in blood pressure in the afferent arterioles of the kidney will result in All of the followingEXCEPT:

a. a decrease in the relase of atrial natriuretic peptide

b. an increase in glomerular filtration rate

c. an increase in glomerular hydrostatic pressure

d. a somewhat greater outpu of urine

e. a decrease in release of renin by juxtaglomerular cells

4) Blood in the renal vein may have a higher concentration of bicarbonate ions than blood in the renal artery because:

a. bicarbonate ions cannot pass the glomerular filter, so blood becomes more concentrated as water eners the nephrons and bicarbonate ions stay behind.

b. the rate of celular respiration is higher in the endothelium of he renal venules than in the endothelium of the renal arterioles

c. newly produced bicarbonate ions (as opposed to filtered bicarbonate ions) are added to the blood by he intercalated cells of the collecting ducts as they secrete hydrogen ions into the tubular fluid

d. hydrogen ions must be added to the venous blood to maintain pH balance, so bicarbonate ons are reabsorbed at the same time to maintain elecrical balance

e. large ions like bicarbonate ions are necessary in the venous blood to help maintan blood colloid osmotic pressure

Explanation / Answer

Ans- An increase in blood pressure in the afferent arterioles of the kidney will result in All of the following except-

d) a somewhat greater optuof urine.

Ans- Blood in the renal vein may have a higher concentration of bicarbonate ions than blood in the renal artery because-

a) bicarbonate ions cannot pass the glomerular filter, so blood becomes more concentrated as water eners the nephrons and bicarbonate ions stay behind.
