what is the main driver of normal quiet ventilation..   a.the H+ concentration in the arterial blood, which is monitored by central chemoreceptors b.the PO2 of the arterial blood, which is monitored by central chemoreceptors   c.the PO2 of the arterial blood, which is monitored by peripheral chemoreceptors   d.the H+ concentration in the CSF, which is monitored by central chemoreceptors   e.the PCO2 of the arterial blood, which is monitored by peripheral chemoreceptors

19.At high altitude alveolar ventilation increases as a result of? a. high PCO2 stimulating central chemoreceptors b. high PCO2 stimulating peripheral chemoreceptors c. low PO2 stimulating central chemoreceptors d. low PO2 stimulating peripheral chemoreceptors e. alkalosis stimulating both central and peripheral chemoreceptors

During inspiration, which of the following does not occur? a. diaphragm contracts b. intrapleural pressure becomes more negative c. intrapulmonary pressure decreases below atmospheric pressure d. lungs move closer to total lung capacity e. thoracic cavity volume decreases

When alveolar ventilation exceeds the needs of cellular respiration there is a/an OA. increase in the hydrogen ion OB. increase in the carbon dioxide C. decrease in the carbon dioxide O D. decrease in the oxygen O E. None of the above concentration in the blood.
