The emerging baby receives oxygen through the umbilical cord. Temporary squeezing of the umbilical cord during the birth process generally, causes no problems, whereas prolonged constriction of the cord is associated with developmental problems.
Explanation:
The umbilical cord is a tube that connects the baby to the placenta and is responsible for the exchange of nutrients, oxygen and excreta. Composed of two arteries and a vein encased in a jelly-like material - Wharton's jelly - the umbilical cord communicates the baby's circulatory system through the navel to the placental vessels and is normally inserted right in the center of this structure. The placenta, in turn, communicates to maternal vessels, making the necessary exchanges.
There are situations where the umbilical cord is tightened during the baby's birth, these situations are normal and most of the time do not cause any problems for either the baby or the mother. However, if prolonged umbilical cord constriction occurs, developmental problems may occur.
