Where in the foetal heart is the foramen ovale located? What type of blood is passed through this foramen?
Between the right and left atrium; oxygenated
Where in the foetal heart is the ductus arteriosus located? What type of blood passes through this duct?
Between the pulmonary artery and aorta; oxygenated
The ductus arteriosus is kept open by what during foetal life?
Prostaglandins
