Passage / Scenario
NoneIn fetal circulation, the ductus venosus diverts blood from which of the following organs?
Correct answer
D
Rationale
The ductus venosus allows oxygen-rich blood from the umbilical vein to bypass the liver and flow into the inferior vena cava, ensuring well-oxygenated blood reaches vital fetal organs. The lungs are bypassed by the foramen ovale and ductus arteriosus, and the heart and kidneys are not bypassed by the ductus venosus.
