A)An increase in the level of carbon dioxide in the blood
B)A decrease in the level of oxygen in the blood
C)An increase in the level of hydrogen ions in the blood
D)An increase in the level of sodium ions in the blood

Accepted Answer

Peripheral chemoreceptors primarily detect changes in the levels of oxygen, carbon dioxide, and hydrogen ions in the blood. Sodium ions are not directly involved in the regulation of breathing and are not detected by peripheral chemoreceptors.
