menstrual cycle how to do work
Answers
The egg travels down the fallopian tubes. If pregnancy doesn't occur, the egg is reabsorbed into the body. Levels of oestrogen and progesterone fall, and the womb lining comes away and leaves the body as a period (the menstrual flow). The time from the release of an egg to the start of a period is around 10 to 16 days.

Explanation:
The length of the menstrual cycle varies from woman to woman, but the average is to have periods every 28 days. Regular cycles that are longer or shorter than this, from 21 to 40 days, are normal.
"The menstrual cycle is the time from the first day of a woman's period to the day before her next period," says Toni Belfield, a specialist in sexual health information, and a trained fertility awareness teacher.
"Girls can start their periods anywhere from age 10 upwards, but the average is around 12 years," says Belfield. "The average age for the menopause (when periods stop) in this country is 50 to 55."
Between the ages of 12 and 52, a woman will have around 480 periods, or fewer if she has any pregnancies.

What happens during the menstrual cycle?
To understand the menstrual cycle, it helps to know about the reproductive organs inside a woman's body. These are:
2 ovaries – where eggs are stored, developed and released
the womb (uterus) – where a fertilised egg implants and a baby develops
the fallopian tubes – two thin tubes that connect the ovaries to the womb
the cervix – the entrance to the womb from the vagina
the vagina
The menstrual cycle is controlled by hormones. In each cycle, rising levels of the hormone oestrogen cause the ovary to develop and release an egg (ovulation). The womb lining also starts to thicken.
In the second half of the cycle, the hormone progesterone helps the womb to prepare for implantation of a developing embryo.
The egg travels down the fallopian tubes. If pregnancy doesn't occur, the egg is reabsorbed into the body. Levels of oestrogen and progesterone fall, and the womb lining comes away and leaves the body as a period (the menstrual flow).
The time from the release of an egg to the start of a period is around 10 to 16 days.
