regulation of systemic arterial blood pressure by chemoreceptor signaling regulation of systemic arterial blood pressure by aortic body chemoreceptor signaling biological_process The process that modulates blood pressure by the action of chemoreceptors found in the aortic bodies and their resultant modulation of the vasomotor center. Chemoreceptors respond to oxygen, carbon dioxide and hydrogen ions.
