Which Structure in the Fetus Allows Blood to Bypass the Immature

Question

Which structure in the fetus allows blood to bypass the immature liver?
A) foramen ovale
B) ductus venosus
C) ductus arteriosus
D) umbilical vein

Accepted Answer

The ductus venosus is a shunt that allows oxygenated blood from the placenta to bypass the immature liver in the fetus and enter the inferior vena cava. This allows the blood to reach the heart and then be pumped to the rest of the body.
