does the umbilical artery carry oxygenated blood to the conceptus
Umbilical artery The umbilical arteries supply deoxygenated blood from the fetus to the placenta. There are usually two umbilical arteries present together with one umbilical vein in the umbilical cord. The umbilical arteries surround the urinary bladder and then carry all the deoxygenated blood out of the fetus through the umbilical cord. Inside the placenta, the umbilical arteries connect with each other at a distance of approximately 5Â mm from the cord insertion in what is called the Hyrtl anastomosis.[1] Subsequently, they branch into chorionic arteries or intraplacental fetal arteries.[2]
Implantation (human embryo) On the endometrium, the apposition is usually made where there is a small crypt in it, perhaps because it increases the area of contact with the rather spherical blastocyst.
Fluid balance These outputs are in balance with the input of ~2500 ml/day.[9]
Bilirubin Hyperbilirubinemia is a higher-than-normal level of bilirubin in the blood. For adults, this is any level above 170 μmol/l and for newborns 340 µmol/l and critical hyperbilirubinemia 425 µmol/l.
