A twisting cord of blood vessels, called the umbilical (um-bilâi-kal) cord, connects the embryo to the placenta. The best intensive care units found in modern hospitals hardly rival the placentaâs life-support capabilities. The yolk sac is another structure vitally important during early development.
The baby growing inside of the mother's uterus (the womb) is called a fetus. The growing fetus is fully dependent on a special organ called the placenta for nourishment. One side of the placenta is attached to the uterus, and the other side is attached to a liquid-filled sac that holds the fetus. A special cord called the umbilical cord links the placenta to the fetus. The mother's blood flows through a thin layer of cells in the wall of the uterus, giving the fetus food and oxygen while removing any wastes like carbon dioxide.
