Schematic diagrams depicting (A) the main components of a monochorionic diamniotic twin gestation. The magnified views in (B) represent the maternal placental circulation (left) and the fetal placental circulation (right) with an inset cartoon (C) representing oxygen transport from mother to the fetuses. Oxygen exchange between maternal hemoglobin and fetal hemoglobin by free diffusion across the interhemal membrane, and is modulated by the oxygen gradient, membrane permeability, and blood flow in both circulations.
