PATHOLOGY

Detailed explanation-1: -Menstruation. Menstruation is one part of a person’s menstrual cycle which includes the shedding of the endometrium (lining of the uterus) that occurs throughout a person’s reproductive life.

Detailed explanation-2: -During a typical menstrual cycle, the inside walls of the uterus grow a soft tissue lining called the endometrium. If you do not get pregnant, the endometrium is shed during menstruation.

Detailed explanation-3: -When pregnancy doesn’t occur, the egg is absorbed back into the body and the thick lining in the uterus is shed, this is your period. Then the cycle begins all over again. Day one of your cycle is the first day of your period. This is when your uterus starts shedding the lining it has built up over the last 28 days.

Detailed explanation-4: -The lining of the uterus (endometrium) starts to thicken. One of the ovaries releases an egg. And then, if the egg isn’t fertilized or a fertilized egg doesn’t attach to the lining of the uterus (implant), the endometrium sheds from the uterus as a menstrual period.
