Uterus: menstrual phase (Days 1-5)
Sloughing of the functional zone has already begun, as evidenced by the lack of surface epithelium, presence of glands at the luminal surface, and missing portions of the functional zone. The thickness of the remaining functional zone indicates that this tissue was taken during the early days of the menstrual phase. 100x
