The layer of the uterus that is shed during menstruation, approximately every 28 days, is the endometrium - this is the spongy mucosal tissue that develops after ovulation under the influence of progesterone to support the fertilised egg should a woman fall pregnant, if the woman doesn't fall pregnant then the endometruim becomes unstable and sheds aka menstruation.
The endometrium is the lining of the uterus. It is the part that is sloughed off during menstruation.
The process in which the endometrium of the uterus is shed from the body is called menstruation.
The Uterus
Menstruation associated with reproduction because menstruation is about cycle of the egg in woman's uterus. Every menstruation, the old egg destroy and came out in the form of blood clots. After that, uterus produce new egg.
Menstruation is one of the phases of the menstrual cycle, whereas the menstrual cycle is the entire reproductive system. During the menstrual cycle an egg is released and to prepare for possible pregnancy the uterus lining plumps-up, if pregnancy doesn't occur the uterus lining sheds (menstruation) so it can start afresh again next cycle.

Your muscles in your uterus are contracting in order to shed the lining in the uterus to rid it from your body.
The process in which the endometrium of the uterus is shed from the body is called menstruation.
The flow of blood and tissue cells from the uterus is called menstruation. During menstruation, the lining of the uterus sheds and is expelled through the vagina. This process is accompanied by the flow of blood, which is a mix of tissue cells, uterine lining, and blood from the ruptured blood vessels in the uterus.
Menstruation
The inflammatory substance responsible for pain during menstruation is prostaglandins. The prostaglandins cause the uterine contractions, but in high quantities it will cause blood vessels supplying the uterus with blood to construct so starve the uterus of blood/oxygen very temporarily, and thus this is what causes the pain during menstruation.
