Which structure allows blood to move from the fetal pulmonary trunk directly into the aorta?
A
Umbilical vein
B
Ductus arteriosus
C
Foramen ovale
D
Ductus venosus
Verified step by step guidance1
Understand the context: In fetal circulation, certain structures bypass the lungs because the fetus does not breathe air; oxygen is provided by the placenta.
Identify the role of the pulmonary trunk and aorta: The pulmonary trunk normally carries blood to the lungs, but in the fetus, blood bypasses the lungs and moves directly into the aorta to supply the rest of the body.
Learn about the ductus arteriosus: This is a fetal structure that connects the pulmonary trunk to the aorta, allowing blood to bypass the lungs and flow directly into systemic circulation.
Differentiate between the other options: The umbilical vein carries oxygenated blood from the placenta to the fetus, the foramen ovale allows blood to move between the right and left atria, and the ductus venosus shunts blood from the umbilical vein to the inferior vena cava, bypassing the liver.
Conclude that the ductus arteriosus is the structure responsible for moving blood from the fetal pulmonary trunk directly into the aorta.
