Which statement about the umbilical vessels is true?

Explanation:
The key idea is how blood moves in the umbilical vessels between mother and fetus. Oxygenated blood travels from the placenta to the fetus through the umbilical vein, delivering oxygen and nutrients to fetal tissues. The two umbilical arteries carry deoxygenated blood from the fetus back to the placenta for exchange. So the true statement is that the umbilical vein carries blood to the fetus. The other statements aren’t accurate because arteries do not bring blood to the fetus, the placenta is the site of exchange rather than the only place blood circulates, and the vein does not carry blood from the fetus to the placenta.
