Umbilical arteries arise from which arteries on each side of the bladder?

• A. Hypogastric
• B. Renal
• C. External iliac
• D. Femoral

Answer: (A)

In fetal circulation, the umbilical arteries arise from the internal iliac arteries, also known as the hypogastric arteries, on each side of the bladder. From there, they travel with the umbilical cord to the placenta, carrying deoxygenated blood away from the fetus for gas exchange. The other arteries listed don’t give rise to the umbilical arteries: the renal arteries go to the kidneys, the external iliac artery supplies the lower limb after passing under the inguinal ligament, and the femoral artery is the continuation of the external iliac in the thigh.
