Quizplus · Accepted Answer

The human respiration rate is most closely correlated to the levels of carbon dioxide (CO2) in the blood. The body primarily monitors CO2 levels to regulate breathing, as an increase in CO2 triggers the urge to breathe to expel the excess CO2. Oxygen levels are also monitored, but the primary driver for the urge to breathe under most conditions is the level of CO2.
