Questions and Answers

Which of the following is true about the stimuli at the various receptors in respiration control?

  • Only concentration of CO2 is important stimulus
  • Only concentration of O2 is important stimulus
  • Concentrations of O2 and CO2 are not important stimuli
  • Concentrations of O2 and CO2 are important stimuli (correct)
  • What happens to the alveolar tensions during breath holding?

  • PO2 rises and PCO2 falls
  • PO2 falls and PCO2 rises (correct)
  • PO2 and PCO2 both rise
  • PO2 and PCO2 both fall
  • What is the primary factor for breaking during breath hold when breathing 100% O2?

  • Hypoxia
  • Hyperventilation
  • Hypercapnia (correct)
  • Lung collapse
  • Breathing 100% O2 increases the tolerance for hypercapnia because
