The endometrium is functionally subdivided into two layers. 1  The stratum functionalis is a thick superficial layer that is sloughed off during menstruation and grows anew during each cycle.  The stratum basalis consists of permanent stromal tissue and deep ends of the uterine glands.
At the end of the menstrual cycle, when no fertilization occurs, the uterus sheds off its lining along with blood. Hence, a menstrual period is the shedding of the uterus lining. The duration of a menstrual period on the average is between three to five days.
