From the Wikipedia entry for "Foramen ovale (heart)":
Normally this opening closes in the first year of life. When the lungs become functional at birth, the pulmonary pressure decreases and the left atrial pressure exceeds that of the right. This forces the septum primum against the septum secundum, functionally closing the foramen ovale. In time the septa eventually fuse, leaving a remnant of the foramen ovale, the fossa ovalis.
In other word, it "changes" for each person shortly after that person's birth.
In the fetal hear the fossa ovalis was known as the foramen ovale, which allows blood to pass from the right to the left atrium, thus bypassing the fetal lungs.
Ligamentum arteriosum and the fossa ovalis. That is to say the arterial ligament and the oval depression (found in the left ventricle).
In the fetal heart, the foramen ovale (or ostium secundum of Born) allows blood to enter the left atrium from the right atrium. It is one of two shunts, the other being the ductus arteriosus, that allows blood entering the right atrium to bypass the pulmonary circulation. Another similar adaptation in the fetus is the ductus venosus. In most individuals, the foramen ovale (pronounced /fɒˈreɪmən oʊˈvɑːli/) closes at birth. It later forms the fossa ovalis.

The open gap which connects the left and right atria of the heart in a fetus. The fetus' pulmonary artery isn't used as it doesn't breathe in air and so when blood is pumped around it's heart it bypasses the pulmonary artery which would normally pump blood to the lungs.
A Patent (Open) Foramen Ovale bypasses the lungs by short circuiting blood flow from the right atrium to the left atrium.
The Foramen Ovale gives rise to the Fossa Ovalis. In most individuals, the foramen ovale closes at birth. It later forms the fossa ovalis.
fossa ovalis
In the fetal hear the fossa ovalis was known as the foramen ovale, which allows blood to pass from the right to the left atrium, thus bypassing the fetal lungs.
the fossa ovalis was the foramen ovale and the ligamentum arteriosum was the ductus arteriosus. They each contributed to shunting blood away from the non-functional lungs in the fetus.
Ligamentum arteriosum and the fossa ovalis. That is to say the arterial ligament and the oval depression (found in the left ventricle).

The ligmentum arteriosum is the remnant of the ductus arteriosus in the fetal heart. The fossa ovalis is the remnant of the foramen ovale.
The ductus arteriosus, formen ovale and ductus veinosus.
The open gap which connects the left and right atria of the heart in a fetus. The fetus' pulmonary artery isn't used as it doesn't breathe in air and so when blood is pumped around it's heart it bypasses the pulmonary artery which would normally pump blood to the lungs.
The foramen ovale closes, becoming part of the interatrial septum. The Ductus arteriosus becomes the ligamentum arteriosum and the ductus venosus becomes the ligamentum venosum.
The Ductus arteriosis allows the oxygenated blood to bypass the non-functioning lungs by going straight from the right ventricle to the aortic arch, instead of going through the pulmonary artery. The Ductus Venosus allows half of the blood from the umbilical vein to be shunted to the inferior vena cava to bypass the babies liver. And the Foramen ovale lets blood go straight from the right atrium to the left atrium, the Ductus Arteriosis is a back up for when blood gets left behind. The foramen ovale closes over at birth to form the fossa ovalis.
