The umbilical cord is formed from the attachment peduncle, which allows the connection between the embryo and the trophoblastic envelope.
The anatomy of the umbilical cord consists of two arteries, which leave the fetus and are directed towards the placenta. In addition, the umbilical cord contains a vein that runs from the placenta to the fetus. Both the arteries and the umbilical vein are in a gel-like tissue, providing strength to the cord and preventing the formation of knots.
