How many arteries and veins are present in the umbilical vessels?

Explanation:
There are two arteries and one vein in the umbilical vessels. In fetal circulation, the two arteries carry deoxygenated blood from the fetus to the placenta, while the single vein carries oxygenated blood from the placenta back to the fetus. This arrangement supports the placenta as the site of gas and nutrient exchange for the developing fetus. After birth, these vessels close and become ligaments—the arteries become the medial umbilical ligaments, and the vein becomes the ligamentum teres hepatis.
