Answer:

Explanation:
Sorry I don't know the answer of this question.
Answer:
The foramen ovale becomes the fossa ovalis as the foramen closes while edge of the septum secundum in right atrium becomes anulus ovalis, so the depression beneath it becomes the fossa ovalis. This enables respiration and circulation independent from the mother's placenta.
Explanation:
The fossa ovalis is the remnant of an interatrial opening, the foramen ovale, which has a significant role in fetal circulation (allowing blood to flow from the right atrium to the left atrium during fetal development)
The shunt that bypasses the lungs is called the foramen ovale. This shunt moves blood from the right atrium of the heart to the left atrium. The ductus arteriosus moves blood from the pulmonary artery to the aorta. Oxygen and nutrients from the mother's blood are sent across the placenta to the fetus.
