where does edema tend to occur in the pregnant woman’s body
Maternal physiological changes in pregnancy Edema, or swelling, of the feet is common during pregnancy, partly because the enlarging uterus compresses veins and lymphatic drainage from the legs.
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]
