The arterial (Botallov) duct is a small vessel located on the lower anterior surface of the aortic arch. The child before the moment of birth arterial duct connects the pulmonary trunk and the aorta, being a link in the embryonic circulation.

The baby’s lungs do not function until they are born, they are asleep and contain a liquid, so a significant mass of blood from the pulmonary artery is sent not to the lungs, but to the arch of the aorta through the arterial duct.

In the pulmonary artery, blood is supplied by the right ventricle. The arterial duct, through the discharge of excess blood, helps to protect the right ventricle from overloading, which is created by high resistance in the asleep lungs. Intrauterine closure of the arterial duct in a child is fraught with the development of right ventricular failure.
