2. The placenta produces glycogen, cholesterol, and fatty acids continuously for fetal use and hormone production.
3. The placental functions include fetal respiration, nutrition, and excretion. To carry out these functions, the placenta is involved in metabolic and transfer activities.
4. The umbilical cord provides a circulatory pathway from the chorionic villi to the embryo.
