Endometrium
The endometrium is the lining of the uterus. It is the part that is sloughed off during menstruation.
endometrium
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.
Menstrual clots are thickened blood that can appear during menstruation, while menstrual tissue is the lining of the uterus that sheds during a period.
Menstrual cycle.
The material flowing from the human female reproductive tract during menstruation is produced by the breakdown of the endometrial lining of the uterus. This tissue and blood are shed during the menstrual cycle if a fertilized egg is not implanted.

The endometrium is the innermost layer of the uterus. It is the layer that is shed during menstruation.
Pain during menstruation. May be caused by pelvic inflammatory disease (a rather nonspecific diagnosis) or by endometriosis (where endometrial tissue occurs NOT in the uterus).
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 thickness of the lining of the uterus decreases between day one and day five of the menstrual cycle primarily due to the shedding of the endometrial tissue during menstruation. This process is triggered by a drop in hormone levels, particularly progesterone, which leads to the breakdown and expulsion of the uterine lining. As menstruation progresses, the lining is sloughed off, resulting in a thinner endometrium by day five. After this phase, hormone levels begin to rise again, preparing the uterus for potential implantation in the following cycle.
