Iliac artery feeder

AORTA

Think of the body's largest blood vessel that branches off just below the heart, supplying major arteries including those to the legs.

The iliac arteries branch off from a major blood vessel that carries oxygen-rich blood from the heart down through the abdomen. That vessel is the aorta, which acts as the body’s main "feeder" for the iliac arteries. The clue plays on this anatomical relationship, using "feeder" to hint at the aorta’s role as the source.
