Figure 4

The maxillary artery (green) is derived from the 1st PAA. The stapedial (red) is derived from the 2nd PAA. The carotid system (purple) derives from the 3rd PAA. The left 4th PAA gives rise to the aortic arch while the right PAA gives rise to the subclavian artery and contributes to the pulmonary arteries (light blue). Finally, the 6th PAA give rise to the ductus arteriosus (dark blue) and the pulmonary arteries (light blue).
