Figure 3: Artery defects.

Figure 3:

A. Diagram of arteries of the heart and their origins from the left/right side of the embryo, illustrating levels of sections shown in B-D. B-D. H&E serial cross-sections through the heart’s arteries, representing different defects in artery development. Sections within a column come from a single heart. Sections from three hearts are shown. B. Wild type. C. Artery missing. D. Abnormal fusion order of arteries along the distal-proximal axis. E. Incidence of embryos with a missing artery. F. Incidence of embryos with an abnormal artery fusion order. LBC/RBC = left and right brachiocephalic arteries, LPA and RPA = left and right pulmonary arteries, A = aorta, P = pulmonary trunk, LA = left atrium, RA = right atrium.
