In most individuals, the foramen ovale closes at birth. It later forms the fossa ovalis
It is one of two fetal cardiac shunts, the other being the ductus arteriosus (which allows blood that still escapes to the right ventricle to bypass the pulmonary circulation). Another similar adaptation in the fetus is the ductus venosus[WP]
