Gas Exchange in the Placenta
Gas Exchange in the Placenta
This medical illustration pictures a mid-sagittal view of a mother with a fetus in utero, including the placenta. An enlarged image of a cross section of the placenta depicts gas exchange within the placenta, showing oxygen in maternal blood vessels traveling to the fetus through the umbilical vein in the umbilical cord, and carbon dioxide leaving the fetus through the umbilical arteries.
