You've sort of answered this question twice in the question itself!
"The PERIOD in the MENSTRUAL cycle which the...in the MENSTRUAL"
The menstrual phase aka menstruation or period.
During the menstrual cycle, the uterus prepares for a possible pregnancy by building up its lining (endometrium). If fertilization does not occur, the uterus sheds this lining during menstruation. The hormones involved in the menstrual cycle regulate these changes in the uterus.
At the end of a menstrual cycle, the unfertilized egg is either absorbed by the body or expelled during menstruation. The lining of the uterus, which thickened in preparation for a possible pregnancy, sheds as menstrual bleeding. This marks the start of a new menstrual cycle.
The uterus has a lining of blood in it. When the unfertilized egg passes through the uterus it sheds this lining which causes the blood to come out.
Hormone levels drop and the uterus lining starts to break down during a woman's menstrual cycle. This typically occurs after ovulation when there is no pregnancy, leading to the shedding of the uterine lining in the form of a menstrual period.
The uterus lining breaks down during menstruation, which occurs approximately every 28 days in women who are not pregnant. The breakdown of the lining is part of the menstrual cycle, which involves shedding of the endometrium in preparation for a new cycle of ovulation.
Ovaries produce eggs which travel to the uterus. There they will either get fertilized by sperm or the the uterus will shed its lining, which causes a period.
Yes. Your uterus is still shedding it's lining, menstruation stage of the menstrual cycle can continue after your period.
because a boy does not have a uterus! the lining of the uterus is renewed every couple of weeks hence the flow (called a period).
The lining of the uterus is shed during the menstrual phase of the menstrual cycle. This is when the body sheds the built-up uterine lining in the absence of a fertilized egg, resulting in menstrual bleeding.
During a woman's menstrual cycle, she will begin to ovulate. During ovulation, the ovary releases an egg. If the egg is not fertilized, it will continue to make its way down into the uterus. The uterus will begin to shed its lining since it is not needed. The lining of the uterus and the egg will be expelled from the vagina. This step of the menstrual cycle is what is refered to as the period.
The uterus lining will come loose and a mentral cycle will begin.
if it is fertilized by sperm it becomes a zygote that embeds itself into the lining on uterus The placenta, which is especially prepared for this event once a month if it is not fertilized it breaks down after a couple of days which signals for the uterus to dispose of the lining in what is seen as menstrual bleeding.
