Is a connection between the pulmonary trunk and the aorta in the fetus?

The second feature of the fetal heart that differs from the postnatal heart is the presence of the ductus arteriosus (DA in diagram). This vessel connects the pulmonary artery to the aorta and allows blood to flow from the pulmonary artery into the aorta, which carries it to the placenta for oxygenation.

What connects the pulmonary trunk to the aorta?

During fetal life, the ductus arteriosus connects the main pulmonary artery and aorta, carrying outflow from the right ventricle to the descending aorta and largely bypassing the lungs.

What is the name of the blood vessel that connects the pulmonary trunk to the aorta prior to birth?

The ductus arteriosus is a normal blood vessel that connects two major arteries — the aorta and the pulmonary artery — that carry blood away from the heart.

What are the fetal shunts?

Abstract. The fetal circulatory system bypasses the lungs and liver with three shunts. The foramen ovale allows the transfer of the blood from the right to the left atrium, and the ductus arteriosus permits the transfer of the blood from the pulmonary artery to the aorta.

What is the last part of a fetus to develop?

Just four weeks after conception, the neural tube along your baby’s back is closing. The baby’s brain and spinal cord will develop from the neural tube. The heart and other organs also are starting to form and the heart begins to beat. Structures necessary to the formation of the eyes and ears develop.
