chemoreceptor, chemoceptor:
1. Any of a group of receptors in the carotid sinus and the aorta that are sensitive to changes in blood oxygen and carbon dioxide levels and that have an effect on the rate and depth of breathing as well as on the heart rate.

chemoreflex
1. A reflex caused by a chemical stimulus.
2. A reflex initiated by the stimulation of chemoreceptors, e.g., of a carotid body.
