Alterations in arterial partial pressure of CO2 (PaCO2) do NOT stimulate the carotid body receptors sufficiently to produce changes in minute ventilation.
a) Changes in PaCO2 stimulate carotid body receptors
b) Changes in PaCO2 do not affect minute ventilation
c) Changes in PaCO2 stimulate central chemoreceptors
d) Changes in PaCO2 stimulate peripheral chemoreceptors
