Foramen ovale
The remnant of foramen ovale found after the developmental stage of the fetus
Fossa ovalis
A shunt that lets oxygenated blood in the umbilical vein to bypass the liver and is essential for norm fetal development
Ductus venosus
The fibrous remnant of the ductus venosus of the fetal circulation
Ligamentum venosum
Within a week of birth, the neonate umbilical vein is obliterated and is replaced by a fibrous cord called the round ligament of the liver also known as
Ligamentum teres hepatis
Carry deoxygenated blood from fetal circulation to the placenta
Umbilical arteries
