What effect does hyperventilation have on the closed buffer systems?
a. It causes them to bind with more H+.
b. It causes them to release more H+.
c. It has no effect on them at all.
d. It increases the affinity of the closed buffer system.
ANS: B
Increased ventilation increases the CO2 removal rate, causing nonbicarbonate buffers to release H+ ions. Decreased ventilation ultimately causes nonbicarbonate buffers to accept more H+ ions.
