Detailed explanation-1: -Oxygen and nutrients from the mother’s blood are transferred across the placenta to the fetus through the umbilical cord. This enriched blood flows through the umbilical vein toward the baby’s liver. There it moves through a shunt called the ductus venosus.
Detailed explanation-2: -The placenta helps to keep your baby alive and healthy during pregnancy. Your blood passes through the placenta and provides oxygen, glucose and nutrients to your baby through the umbilical cord. The placenta can also filter out harmful waste and carbon dioxide from your baby’s blood.
Detailed explanation-3: -The placenta plays a key role in the nutrition of the fetus. It mediates the active transport of nutrients and metabolic wastes across the barrier separating maternal and fetal compartments, as well as modifying the composition of some nutrients through its own metabolic activity.
Detailed explanation-4: -The umbilical vein carries oxygenated, nutrient-rich blood from the placenta to the fetus, and the umbilical arteries carry deoxygenated, nutrient-depleted blood from the fetus to the placenta (Figure 2.2).
