Embryology (Vasculature Development) Flashcards
Right Fourth Aortic Arch Developes Into
- proximal portion of right subclavian artery
Coarctation of Aorta
- Constriction of aorta
- Occurs adjacent to the entrance of the ductus arteriosus
Aortic Sac Developes Into
- ascending aorta
- part of arch of aorta
- brachiocephalic artery
Proximal Right Anterior Cardinal Vein Develops Into
- Superior vena cava
Seventh Intersegmental Arteries Develope Into
- parts of right subclavian artery and all of left subclavian artery
Three Vitelline Arteries Develop Into
- unpaired arteries of the adult that supply the foregut, midgut, and hindgut
Ductus Venosus Develops Into
- Ligamentum venosum
Supracardinal Veins Develop Into
- Azygos system of veins
- Part of the inferior vena cava
Distal Portion of Left Umbilical Vein Develops Into What Before Birth?
- Umbilical vein
Left Fourth Aortic Arch Developes Into
- aortic arch between left common carotid artery and left subclavian artery
Proximal Right & Left Sixth Aortic Arches Develope Into
- proximal parts of right and left pulmonary arteries
Left Umbilical Vein Develops Into
- Ligamentum teres hepatis
Right Dorsal Aorta Developes Into
- intermediate portion of right subclavian artery
Third Aortic Arches Develope Into
- common carotid arteries
- proximal portions of the internal carotid arteries
- external carotid arteries
Truncus Arteriosus Develops Into
- Pulmonary trunk
Umbilical Arteries Job & What They Develop Into
- carry deoxygenated blood from the embryo to the placenta
- ligamentous remnants arising from the internal iliac artery
Left Distal Aorta Developes Into
- descending aorta
Distal Left Sixth Aortic Arch Developes Into
- ductus arteriosus (becomes ligamentum arteriosum)
Anterior vs. Posterior Cardinal Vein Drainage
Anterior - head & neck region
Posterior - remainder of embryo
