[6] The aortic bodies measure partial gas pressures and the composition of arterial blood flowing past it.

[2] Aortic bodies are more sensitive detectors of total arterial blood oxygen content than the carotid body chemoreceptors, which are more sensitive detectors of the partial pressure of oxygen in the arterial blood.

[8] The aortic bodies give feedback to the medulla oblongata, specifically to the dorsal respiratory group, via the afferent branches of the vagus nerve (cranial nerve X).

[1][3] The medulla oblongata, in turn, regulates breathing and blood pressure.

[vague] These bodies detect blood pressure and are involving in passing out and Postural orthostatic tachycardia syndrome.
