is the blood in the umbilical vein of the fetal pig oxygenated or deoxygenated
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 5 mm from the cord insertion in what is called the Hyrtl anastomosis.he umbilical arteries are actually the latter of the internal iliac arteries (anterior division of) that supply the hind limbs with blood and nutrients in the fetus. The umbilical arteries are one of two arteries in the human body, that carry deoxygenated blood, the other being the pulmonary arteries.
