Aorticum, Glomus

Small clusters of chemoreceptive and supporting Cells located near the ARCH OF THE Aorta; the Pulmonary Arteries; and the coronary Arteries. The aortic bodies sense PH; Carbon Dioxide; and Oxygen concentrations in the Blood and participate in the control of Respiration. The aortic bodies should not be confused with the Para-Aortic Bodies in the Abdomen (which are sometimes also called aortic bodies).
