The lungs and kidneys are the primary acid-excreting orgAnswer. The lungs excrete only volatile acid (i.e., the CO₂ arising from dissociating H₂CO₃), whereas the kidneys excrete primarily fixed acids. The lungs can excrete large quantities of CO₂ in minutes, whereas the kidneys remove fixed acids at a much slower pace (hours to days).
