The menstruation cycle refers to the cycles in which a woman's uterus grows and sheds a lining (the endometrium) which could support the development of a fertilised egg. It typically occurs in 28 day cycles, so a woman generally gets her period every 28 days.
Answer:
The menstruation cycle refers to the cycles in which a woman’s uterus grows and sheds a lining (the endometrium) which could support the development of a fertilised egg. It typically occurs in 28 day cycles, so a woman generally gets her period every 28 days. However, cycle length may be as short as 21 days or as long as 40 days in some women. The inner lining of the uterus (the endometrium) goes through three phases during the typically 28 day menstrual cycle: the menstrual phase (days 1-5), the proliferative phase (days 6-14) and the secretory phase (days 15-28).
The ovarian cycle, refers to the cycle in which a woman’s ovaries prepare an egg to be released during ovulation. It is divided into two phases: the follicular phase (days 1-14) and the luteal phase (days 15-28), during which different levels of hormones are released. These two cycle occur in a synchronised manner; day 1 of the ovarian cycle is always also day 1 of the menstrual cycle.
Day 1 of the menstrual cycle coincides with the start of a woman’s period (menstrual bleeding) in which the uterus sheds the lining (endometrium) built up in the previous menstrual cycle. The lining of the uterus is regrown during each menstrual cycle. Menstrual bleeding typically continues for 3-5 days in what is known as the menstrual phase of the cycle. Between 50-150ml of blood is released during this period.
