Heart Outflow Tract (Carnegie Stage 14) EFIC

EFIC images are from an episcopic data set prepared from a human embryo at Carnegie stage 14, representing the end of the fifth week of development.


B cut in frontal fashion at the junction of the outflow tract with the pharyngeal mesenchyme, shows the origins of the pharyngeal arch arteries from the aortic sac. The back wall of the sac, shown by the star, is the putative aortopulmonary septum. The two single-headed arrows show the extent of the pericardial cavity.

Sixth Arch Artery

  • right arch - proximal part persists as right pulmonary artery, distal part degenerates
  • left arch - left pulmonary artery and ductus arteriosus
  • See Pharyngeal arches
