The external iliac artery branches into the uterine artery, which then branches into the arcuate artery. The arcuate artery then gives off branches to the straight arteries, which supply the basal layer of the endometrium. From the straight arteries, blood flows into the spiral arteries, which supply the functional layer of the endometrium. Therefore, the correct order is uterine, arcuate, radial (straight), spiral.
