Question

Which blood vessel carries deoxygenated blood back to placenta

• A. Umbilical Artery
• B. Umbilical vein
• C. Uterine artery
• D. Descending aorta

Answer 1

The Correct Option is A

In human anatomy, the circulatory connection between the fetus and the placenta is crucial for exchanging nutrients, gases, and waste products. The primary vessels involved in this exchange are the umbilical arteries and umbilical vein.

The umbilical artery is responsible for carrying deoxygenated blood and waste products from the fetus back to the placenta. In contrast, the umbilical vein carries oxygenated blood from the placenta to the fetus, supplying the vital oxygen and nutrients needed for fetal development.

Therefore, among the options provided:

• Umbilical Artery
• Umbilical Vein
• Uterine Artery
• Descending Aorta

The correct answer is the Umbilical Artery, as it is the vessel that carries deoxygenated blood back to the placenta.
