The cycle starts with menstruation.
From day 1 to 5 of the cycle, a drop in the level of the hormone progesterone causes the uterus lining to break down (menstruation), it is released as blood through the vagina.
From day 6 to 10, The ovaries produce estrogen which will cause the uterus lining to rebuild. Another hormone FSH ( follicle stimulating hormone) produced in the brain (especifically, the pituitary gland) causes one of the follicles in the ovary to mature. A follicle contains an egg cell.
From day 11 to 15, the level of estrogen drops and the pituitary gland in the brain produces a hormone called LH (lutenizing hormone), which will trigger the release of the egg cell from the matured follicle (this is called ovulation).
From day 16 to 20: the remains of the follicle in the ovary (now called Corpus luteum) will secrete progesterone, which will keep the uterus lining thick, in case fertilization occurs between a sperm cell and the newly released egg cell.
From day 17 to 27, the Corpus Luteum breaks down causing a drop in the level of progesterone, which will trigger menstruation and the cycle re-starts.
During the menstrual cycle, the lining of the uterus thickens in preparation for a potential pregnancy. An egg is released from the ovary during ovulation which can be fertilized by sperm. If fertilization does not occur, the uterine lining is shed during menstruation.

Can you see the egg in your menstrual cycle?
No, the egg itself is microscopic and cannot be seen during the menstrual cycle. The egg is released from the ovary during ovulation, which typically occurs in the middle of the menstrual cycle.
Which days during the menstrual cycle does menstruation menses occur?
Menstruation, or menses, typically occurs during the first few days of the menstrual cycle. This is when the uterine lining sheds if pregnancy does not occur.
How do the estrous and menstrual cycles compare?
The estrous cycle occurs in most mammals, including dogs and cats, and is typically shorter and more predictable than the menstrual cycle in humans. In the estrous cycle, females are only sexually receptive during a specific period, while in the menstrual cycle in humans, women are sexually receptive throughout the cycle but can only conceive during ovulation.
What are the key differences between the menstrual cycle and the estrous cycle in female reproductive physiology?
The key difference between the menstrual cycle and the estrous cycle is that the menstrual cycle occurs in humans and some primates, while the estrous cycle occurs in most other mammals. In the menstrual cycle, females have a monthly period of bleeding, while in the estrous cycle, females experience a period of sexual receptivity known as "heat" or "estrus." Additionally, in the menstrual cycle, females can conceive at any time during their cycle, while in the estrous cycle, females are only fertile during specific times when they are in estrus.
When is a woman's ovulation time typically during her menstrual cycle"?
A woman's ovulation time typically occurs around the middle of her menstrual cycle, usually around day 14 for a 28-day cycle.

What occurs in a woman's body during a menstrual cycle?
The egg matures in the ovary and then released and into the uterus.
When is a woman's ovulation time typically during her menstrual cycle"?
A woman's ovulation time typically occurs around the middle of her menstrual cycle, usually around day 14 for a 28-day cycle.
What role does ovulation play in the menstrual cycle"?
Ovulation is the release of an egg from the ovary, which typically occurs around the middle of the menstrual cycle. It is a crucial step in the menstrual cycle as it is necessary for fertilization to occur. If the egg is not fertilized, it will disintegrate and be shed during menstruation.
Stage of mentrual cycle during which blood tissue and an unfertilized ovum are discharged?
The stage of the menstrual cycle during which blood, tissue, and an unfertilized ovum are discharged is known as menstruation, or the menstrual period. This occurs in the beginning of the menstrual cycle when the uterine lining sheds due to the absence of a fertilized egg.
When does menstrual flow takes place?
Menstrual flow typically occurs during the menstrual phase of the menstrual cycle, which is when a woman sheds the lining of the uterus. This usually happens about once a month, lasting anywhere from 2 to 7 days. The menstrual phase is the first phase of the menstrual cycle.
What happens in the ovulation phase of the menstrual cycle?
During ovulation, an egg is released from the ovary and travels down the fallopian tube, where it can be fertilized by sperm. This typically occurs around the middle of the menstrual cycle.
What occurs on the 14 day of the menstrual cycle?
On the 14th day of a typical 28-day menstrual cycle, ovulation usually occurs. This is when the ovary releases an egg, which can then be fertilized by sperm. Ovulation is a key part of the menstrual cycle and is the most fertile time for conception.
