MEDICAL PHYSIOLOGY

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. This allows some of the blood to go to the liver.

Detailed explanation-2: -Your blood passes through the placenta and provides oxygen, glucose and nutrients to your baby through the umbilical cord.

Detailed explanation-3: -The umbilical cord connects to the baby’s abdomen from the placenta, which in turn is connected to the mother’s uterus. The placenta is responsible for producing pregnancy hormones, as well as hosting important nutritional exchanges between the mother and baby’s blood supply.

Detailed explanation-4: -Nutrient and drug transfer across the placenta are by passive diffusion, facilitated diffusion, active transport, and pinocytosis. Placental drug transfer is dependent on the physical properties of the placental membrane and on the pharmacological properties of the drug.
