Abstract

The transfer of oxygen from the maternal organism to the fetal tissue is a complex mechanism: As indicated in fig, 1 oxygen is (1) transported to the placenta by maternal placental flow, (2) transferred to the fetal umbilical blood, (3) delivered via the fetal arteries to the fetal capillaries and finally (5) transferred by diffusion to the fetal mitochondria.
