The aortic arches or pharyngeal arch arteries are a series of six paired embryological vascular structures which give rise to several major arteries. They are ventral to the dorsal aorta and arise from the aortic sac.
Famous quotes containing the word arches:
“The lean cats of the arches of the churches,
Thats the old world. In the new, all men are priests.”
—Wallace Stevens (18791955)
