twisting and compression. This property serves to protect the critical vascular lifeline between the placenta and fetus.
The umbilical cord protects the fetal vessels that connect the placenta and fetus. The cord is cut at the time of the delivery and immediately its cut surface of its stump is closely examined. If any abnormalities are detected anywhere in these structures - the amnion, the chorion, and the chorionic villi, the placenta and the umbilical cord as well as the placement of the blood vessels in it, the pediatrician will suspect other associated congenital anomalies in the fetus and take the necessary action.
The placenta is where the blood vessels of the mother and the embryo intertwine but do not join. Its function is to facilitate the exchange of oxygen, nutrients, and waste materials between the mother and the embryo. The placenta covers about a quarter of the uterine surface, thus providing a large surface area for such an exchange. By eighteenth to twentieth week of pregnancy, the placenta is fully formed, and is about 450 gms at birth.
The placenta grows during pregnancy to keep up with the nutritional demands of the growing and developing fetus. If there is a reduction in the maternal blood flow to the placenta,
