Menstruation is the shedding of the endometrial lining.
As the shedding occurs, small amounts of bleeding result as the tissue detaches andthe surface heals. The amount of menstruation is determined by the amount of lining and the amount of bleeding. Just as the amount of moisture in the mouth varies from day to day, the amount of urine varies from voiding to voiding, the pulse rate varies from hour to hour, and many other variations in our physiology, menstrual amount is not the same month to month.
