Chemoreceptors in the circulatory system detect changes in circulating pCO2. If CO2 concentrations get too high, the rate of ventilation increases. Why does this make sense?
A)Actually it doesn't make sense. There is no relationship between CO2 and ventilation rate. B)It makes sense because CO2 is formed from O2, and therefore CO2 is a sign that oxygen is being consumed. C)It makes sense because tissues that are more actively working produce more CO2. D)It makes sense because hemoglobin carries CO2 and therefore blocks oxygen binding to the heme site, creating an oxygen deficiency.
