|Latin||Glomus aorticum, corpora paraaortica|
Some sources equate the "aortic bodies" and "paraaortic bodies", while other sources explicitly distinguish between the two.

It measures changes in blood pressure and the composition of arterial blood flowing past it, including the partial pressures of oxygen and carbon dioxide. The chemoreceptors responsible for sensing changes in blood gases are called glomus cells.
A paraganglioma is a tumor that may involve the aortic body.
Swelling can also occur.
