Before birth, which of the following structures connects the right and left auricles of the heart?
- A. Umbilical vein
- B. Foramen ovale
- C. Ductus arteriosus
- D. Ductus venosus
Correct Answer: B
Rationale: The foramen ovale is a fetal cardiac structure that allows blood to bypass the lungs by shunting blood from the right atrium to the left atrium. The umbilical vein carries oxygenated blood from the placenta to the fetus. The ductus arteriosus shunts blood from the pulmonary artery to the aorta. The ductus venosus connects the umbilical vein to the inferior vena cava.
