<prompt> The ventilatory response to hypoxia:Is independent of PaCO2Is more dependent on aortic than carotid chemoreceptorsIs exaggerated by hypoxia of the medullary chemoreceptorsBears an inverse linear relationship to arterial oxygen content  <response>: Ans. D. Bears an inverse linear relationship to arterial oxygen contentAn inverse relationship exists between hypoxia-induced hyperventilation and oxygen content. Hypoxia-induced hyperventilation is dependent on PaCO2 and more on carotid than aortic chemoreceptors.
