Foramen ovale ...i take a medical assistant course
That is a good question! You get the oxygenated blood from the placenta via umbilical vein in case of the fetus. This vein enters the liver of the fetus. The blood then goes to right atrium of the fetus. The lungs are closed in the fetus. So the blood goes to left atrium through foramen ovale to bypass the pulmonary circulation of the fetus. After the birth of the baby, baby takes the first breath. The lungs get inflated. Blood starts to flow via lungs. This closes the foramen ovale. The marking remains there on the wall between both the atria.
The ductus arteriosus closes at birth in pigs and becomes the ligamentum arteriosum. This allows the pulmonary artery to function properly.
