How is the renal tubule excretion of ammonia involed in maintaining the acid-base balance?
Decrease in blood pH accelerates tubule excretion of both hydrogen and ammonia. Increase in blood pH produces opposite, thus maintaining balance
Reason hyperventilation can result in loss of consciousness.
Increase inhydrogen ion concentration above certain level depress the CNS and therefore produces symptoms such as disorientation and coma
