2. What is menstruation??
The process of shedding the lining
of the uterus (endometrium)
This is the body’s way of preparing the female for
pregnancy each month
When fertilization does not occur, the uterine
lining is not needed because there is no
pregnancy. Therefore the lining sheds
3. Menstrual Cycle
The average is 28 days, but ranges from 21-35 days
Days 1-5 are when a female has her period
After the period, an ovum is matured in the ovary
The uterine lining builds up blood and tissue
The mature ovum is released
If fertilized, it attaches to the uterine lining
If not fertilized, lining breaks down & there’s
another period
5. How to create your
menstrual cycle:
Use info in book, pg 25
You can make a pie chart, calendar, graph,
etc to represent the menstrual cycle
Use an average 28 day cycle. Include:
Days 1-5
Days 6-11
Days 12-16
Days 17-28
