Question 1 of 5
Which fetal structure is responsible for carrying oxygenated blood from the placenta to the fetus?
Correct Answer: D
Rationale: The correct answer is D: Umbilical vein. The umbilical vein carries oxygenated blood from the placenta to the fetus. This is because the placenta acts as the organ of gas exchange during fetal development. Oxygenated blood from the mother is transferred to the fetus through the umbilical vein. The other choices are incorrect because:
A) Ductus arteriosus is a fetal blood vessel that connects the pulmonary artery to the aorta, bypassing the lungs.
B) Umbilical artery carries deoxygenated blood from the fetus to the placenta.
C) Portal vein carries nutrient-rich blood from the intestines to the liver, not from the placenta to the fetus.
