Detailed explanation-1: -In order to sustain appropriate fetal development the mother must provide glucose, amino acids and fatty acids, which are transported to the fetus across the placenta.
Detailed explanation-2: -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.
Detailed explanation-3: -The exchange of nutrients between placenta and fetus involves three major mechanisms: (1) direct placental transfer of nutrients from the maternal to the fetal plasma; (2) placental metabolism and consumption of nutrients; (3) placental metabolism of nutrient substrates to alternate substrate forms.
