endomoetrium
The endometrium is the lining of the uterus. It is the part that is sloughed off during menstruation.
When a female reaches puberty, the uterus sheds an unfertilized egg along with the lining of the endometrium during menstruation. This process is part of the menstrual cycle, which typically occurs monthly. The shedding occurs if the egg is not fertilized by sperm, signaling the body to prepare for a new cycle. Hormonal changes regulate this process, marking the transition into reproductive maturity.
The entry of the uterus is called the cervix. It is the narrow, lower part of the uterus that connects to the vagina. The cervix allows menstrual blood to flow out of the uterus during menstruation and also serves as the passageway for sperm to enter the uterus during intercourse.

The lining of the uterus breaks down and is shed during menstruation if fertilization does not occur.
The uterine lining builds-up following ovulation in preparation for possible pregnancy, to allow the zygote to implant and nourish the growing 'baby'. If pregnancy doesn't occur the drop in progesterone triggers the uterus lining to break down, this is called menstruation.
The uterine lining is the tissue that builds up in the uterus each month to prepare for a potential pregnancy. A blood clot, on the other hand, is a clump of blood that can form during menstruation. The uterine lining sheds during menstruation, while blood clots are a normal part of the menstrual process but can sometimes be larger than usual and cause discomfort.
During menstruation, the body sheds the endometrial lining of the uterus, which consists of tissue, blood, and mucus. This lining thickens throughout the menstrual cycle in preparation for a potential pregnancy. If fertilization does not occur, hormonal changes trigger the shedding of this tissue, resulting in menstrual flow. This process is a key part of the menstrual cycle and reproductive health.
The muscles of the uterus called the myometrium are cramping from the constant movement to shed the uterus' lining.
The uterus is a female reproductive organ. It is part of the female reproductive system and plays a key role in menstruation, pregnancy, and childbirth.
The blood from your period comes out of the vagina, through the cervix, which is the lower part of the uterus. It is a normal part of the menstrual cycle for the lining of the uterus to shed each month during menstruation.
Men don't actually have a counterpart to menstruation. The main purpose of menstruation is to get rid of a lining in the uterus that was originally designed to be something that a fertilized egg can implant onto, which will then be nourished by the lining. Since men don't have a uterus, and can't become pregnant, there's nothing similar in men.
