No function in adult: This is the adult anatomic footprint of the normal path of oxygenated blood from the uterus to bypass the fetal lungs & provide oxygen to the fetus's body. This path is in the wall between the fetus's left & right atria. At birth, this hole immediately closes, putting baby blood in the lungs. In adults, this closure may not be complete (patent for amen ovale) & blood may shunt across the atria.
Created for people with ongoing healthcare needs but benefits everyone.
