What is the distribution of the common iliac artery?

• A. Internal and External Iliac Arteries
• B. Axillary and Brachial Arteries
• C. Pulmonary and Bronchial Arteries
• D. Femoral and Popliteal Arteries

Answer: (A)

The common iliac artery splits into two branches: the internal iliac and the external iliac. The internal iliac supplies pelvic organs and the gluteal region, while the external iliac travels downward and becomes the femoral artery to supply the lower limb. This division is what defines the distribution of the common iliac artery. The other options point to arteries in different regions (upper limb, lungs) or to arteries downstream from the external iliac, not its division.
