Summary

[edit]
Description Fig. 60. — The Umbilical Vessels about the Time of Birth. The umbilical vein (a) conveys placental blood to the fetus. At a' it is joined by the portal vein, the combined trunk forming the ductus venosus. The arrows indicate the course of the blood to the heart. The blood passes from the fetus back to the placenta through the two umbilical arteries (b and b'), only the left of which is clearly seen in the picture. It was chiefly through the umbilical vein and the umbilical arteries that fatal infections of the child were so prone to occur in former years. These vessels become obliterated after birth.
