Question
Blood in the renal vein may have a high concentration of bicarbonate ions than blood in the renal artery because:
a. bicarbonate ions cannot pass the golmerular filter, so blood becomes more concentrated as water enters the nephrons and bicarbonate ions stay behind
b. the rate of the cullular respiration is higher in the endothelium of the 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 boood by intercalated cells of the collecting ducts as they secrete hydrogen ions in the tubular fluid.
d. hydrogen ions must be added to venous blood to maintain pH balance, so bicarbonate ions are reabsorbed at the same time to maintain electrical balance
e.large ions like biccarbonate ions are necessary in the venous blood to help maintain blood colloid osmotic pressure
Explanation / Answer
d. hydrogen ions must be added to venous blood to maintain pH balance, so bicarbonate ions are reabsorbed at the same time to maintain electrical balance
