|contributors to the site. The good news is Embryology will remain online and I will continue my association with UNSW Australia. I look forward to updating and including the many exciting new discoveries in Embryology!|

The peripheral circulation, both arterial and venous, are extensively remodelled with embryonic and fetal development. The purpose of this current page is to provide a central resource link to this topic of adult circulatory organization from the embryonic vasculature. Due to the extensive developmental remodelling there are a large number of variations in vascular organization and agenesis.

Reconstruction of Carnegie Embryo No. 390 arterial system.
- Arise with ascent and inferior branches lost
- Sequential, 25% population have 2 or more renal arteries
- branch of abdominal aorta, divides into 4-5 branches
- each gives off small branches to suprarenal glands, ureter, surrounding cellular tissue and muscles
Note: Frequently a second renal artery (inferior renal) from abdominal aorta at a lower level, supplies lower portion of kidney
See the review describing the variations in adult renal artery and vein organization. of renal vascular anomalies shown in adults using computed tomography. The images below are from that review.
Coronary Arteries Timeline
- Carnegie stage 14 or Carnegie stage 15 - A plexus of blind epicardial capillaries appears on the heart in Carnegie
- Carnegie stage 15, Carnegie stage 16, or Carnegie stage 17 - acquires a coronary sinus connection
- Carnegie stage 18 - connection of the proximal coronary arteries to the aorta.
Mouse Coronary Vessels

A recent study, using several species including human, has shown that the caudal cardinal veins are the only contributors to the inferior caval (IVC) and azygos veins.
- Carnegie stage 11 to Carnegie stage 15 - caudal cardinal veins extended caudally from the common cardinal vein.
- Carnegie stage 15 to Carnegie stage 18 - caudal cardinal veins sprout ventrally form the sub cardinal vein plexus .
- then caudal part of the left caudal cardinal vein regresses.
- Inferior vena cava - infrarenal part from the right caudal cardinal vein; renal part from subcardinal veins.
- Azygos veins - from the remaining cranial part or sprouting of the caudal cardinal veins.
See the review describing the variations in adult renal artery and vein organization of renal vascular anomalies shown in adults using computed tomography. The images below are from that review.
