Description:

This FlashTM animation traces prenatal circulation, foramen ovale closure with the first breath and post natal circulation. It is presented as a stylized view of a four chambered heart, with major vessels and miniature lungs and liver. It begins with an empty heart and demonstrates the path of flow with a stepwise progression of each chamber filling and emptying in sequence. It then plays a continuously beating prenatal heart, with arrows tracing the major arterial and minor pulmonary paths. Next it depicts the change in atrial pressure with the first breath and the change in flow due to foramen ovale closure. It ends with a continuously beating post natal heart, showing the regression of the ductus arteriosus and other fetal vessels, along with arrows tracing the venous and arterial paths.
