Into what do the abdominal arteries bifurcate?

• A. R and L common femoral arteries
• B. R and L common renal arteries
• C. R and L common iliac arteries
• D. R and L common carotid arteries

Answer: (C)

The abdominal arteries, specifically the abdominal aorta, bifurcate into the right and left common iliac arteries. This bifurcation typically occurs at the level of the fourth lumbar vertebra (L4) and is a critical transition point in the vascular anatomy of the lower body.

Understanding this bifurcation is essential because the common iliac arteries further divide into the internal and external iliac arteries, which supply blood to the pelvis, lower limbs, and other structures. This anatomical detail is fundamental for procedures involving vascular intervention or imaging in the abdominal and pelvic regions.

The other options represent different sets of arteries that serve various regions of the body but do not directly relate to the bifurcation of the abdominal aorta. The correct identification of the common iliac arteries reinforces the key anatomical knowledge necessary for anyone studying interventional radiology or abdominal anatomy.
