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.

Question 2

What factor would limit the ability of the H2CO3/HCO3 buffer system to perform efficiently?
 
  a. Temperature rise of more than 3 C
  b. Inadequate amount of 2,3-DPG in the blood
  c. Increased production of nonvolatile acids
  d. Lungs failing to excrete adequate levels of CO2

Answer to Question 1

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.

Answer to Question 2

ANS: D
For example, volatile acid (H2CO3) accumulates only if ventilation cannot eliminate CO2 fast enough to keep up with the body's CO2 production.
