Chemoreceptors in the circulatory system detect changes in circulating pCO2. If CO2 concentrations get too high, the rate of ven

A. It makes sense because CO2 is formed from O2 and, therefore, CO2 is a sign that oxygen is being consumed.
B. It makes sense because tissues that are more actively working produce more CO2 and, therefore, need more O2.
C. Actually, it does not make sense. There is no relationship between CO2 and ventilation rate.
D. It makes sense because hemoglobin carries CO2 and, therefore, blocks oxygen binding to the heme site, creating an oxygen deficiency.
