Why do girls get periods?!


Question: Why do girls get periods.?
Answers:
shedding the lining of their uterus. If you don't shed the lining, it builds up and can cause uteran cancer (im not sure if i spelled "uteran" right but it's cancer of the uterus). Som people don't have periods bc of PCOS or other problems, and need to take medication so that they can lower their chances of cancer and other side effects. When you are pregnant, the egg has to have something to attach to and your body allows your uteran walls to keep the lining, becoming a relatively thick layer. hope this helpsHealth Question & Answer

It takes about 28 days from the time the egg leaves the ovary. While it travels down the fallopian tube, a sort of cushion builds up in the uterus. It's spongy substances that becomes engorged with blood in order to receive a fertilized egg. This becomes the embryo protection. However, when no fertilization takes place, the egg is reabsorbed and the spongy, blood filled lining of the uterus, sloughs off, (pronounced, sluffs). Once this happens, the only place left for it to go is out. Thus you get your period. Hope that explains alright for you.Health Question & Answer

In my own words, a layer coats the inside of the uterus in anticipation of a fertilized egg implanting into the wall. This layer is the food for the embryo to grow. Once it is not needed it is flushed out. That "layer" is made up of blood mostly and other fluids. The body is on a cycle of ovulation, fertile period and than menstruation. The cycle repeats. This is associated with hormone changes in the woman. When many woman live or work together in close contact day in and out, their cycles often sync. It is the miracle of God.Health Question & Answer
