Answers
Answer:
Fetal glucose comes almost exclusively from placental transport. Most fetuses, including the human fetus, require a glucose concentration of 4 to 8 mg/kg/min. The fetal brain, erythrocytes, and adrenal medulla rely entirely on glucose as a metabolic fuel.
The placenta is an organ that develops in your uterus during pregnancy. This structure provides oxygen and nutrients to your growing baby and removes waste products from your baby's blood. The placenta attaches to the wall of your uterus, and your baby's umbilical cord arises from it
