Accepted Answer

Ventilation refers to the process of inhaling and exhaling air in and out of the lungs. It has two phases: inhalation, where air is drawn into the lungs, and exhalation, where air is expelled from the lungs. Option A refers to the role of the lungs in regulating blood pH, which is part of the respiratory system but not specifically ventilation. Option B refers to the process of oxygen transportation by hemoglobin, which is also part of the respiratory system but not specifically ventilation. Option D refers to a non-existent acronym.
