endomoetrium
It is the endometrium - more specifically the stratum functionalis. The stratum basalis forms a new functionalis after menstruation.
The lining of the uterus that is discharged during the menstrual phase is known as the endometrium. The endometrium has two layers: the functional layer and the basal layer.
The uterine lining that sheds during menstruation is the endometrium.

The endometrium is the lining of the uterus. It is the part that is sloughed off during menstruation.

The muscles of the uterus called the myometrium are cramping from the constant movement to shed the uterus' lining.
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.
The endometrium (outermost lining of the uterus that is shedded each menstruation) is usually the part of the uterus where cancer prevails since it must proliferate quickly everymonth making the stem cells sensative to mutations. It is cancer of the uterus.
The whole edometrium is shed away during the menstruation, except the basal layer. To shed away the endometrium is the function of the menstruation.
The ovarian cycle and the uterine cycle are part of the same cycle, the reproductive cycle. Ovulation occurs and if the egg isn't fertilised the uterine lining sheds as menstruation.
They also cause the muscles of the uterus to contract, thus helping the uterus shed the lining built up during the first part of a woman's cycle.
Women have menstrual periods because this is a part of our reproductive cycle. Every cycle we ovulate and the uterus builds-up to prepare for possible pregnancy to care for the fetus, if a woman doesn't fall pregnant then the uterus lining sheds so it can start a fresh next cycle.
The bottom part of the uterus is the cervix.
The placenta will be attached to the uterus, but it is not part of it. The uterus is a muscle and is part of basic female human anatomy. The placenta is an organ which is formed after conception.
the cervix is the upper part of the vagina/lower part of the uterus. during the latent phase of labor, the cervix begins dilating. (opening). then the contractions of the uterus intensify and push the fetus past the cervix and out through the vagina
