Uterus: secretory phase (Days 14-26)
Late in the secretory phase, the functional zone is thick with widely sacculated, saw-toothed glands. These glands are quite distended, displaying secretory product in their lumens. Coils of a spiral artery can readily be seen zigzagging through the endometrium at the junction of the basal and functional zones. 200x
