    Whole blood citrate concentration was measured simultaneously in the umbilical vein, fetal femoral artery and maternal artery in seven chronically catheterised pregnant ewes and their fetuses. The mean citrate concentration was 0-321 mmoles/litre in the umbilical vein, 0-297 mmoles/litre in the fetal femoral artery and 0-095 mmoles/litre in the maternal artery. The mean concentration difference for citrate across the fetal placental circulation was 0-024 mmoles/litre but this was not statistically significant (P less than 0-1).

    Fetal Circulation

    Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
    Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
