List the two mechanisms by which tubule and collecting duct cells generate new HCO3−.
What two quantities make up “H1 excretion”? Why can this term beequated with “contribution of new HCO32 to the plasma”?
The collecting duct Secrete either:
if plasma pH <7.4; or
if plasma pH > 7.4
(select either H+ or HCO3-)
