Question

Quizplus · Accepted Answer

The foramen ovale is a fetal heart structure that allows blood to bypass the lungs and flow from the right atrium to the left atrium. After birth, when the baby takes its first breath and the lungs become functional, the foramen ovale closes to prevent shunting of blood. If it fails to close after birth, blood would shunt from the left atrium into the right atrium, causing complications.
