Chemoreceptors in the Circulatory System Detect Changes in Circulating PCO₂

question 97

Multiple Choice

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.
