Menstruation

Menstruation

The female ovary produces eggs every month and the uterus also prepares itself to receive the fertilized egg .

These preparations include:

1. The uterus lining becomes thick and spongy.
2. It becomes enriched with blood and tissue in order to nourish the embryo.

• However, if the egg is not fertilized, the lining is not needed anymore. 
• The unfertilized egg too lives for just one day. 
• After that, this lining slowly breaks and comes out of the vagina in the form of blood and mucus.
• It is a cyclic process which occurs every month and lasts for 2-8 days . This whole process is known as menstruation .
• The menstrual cycle begins once a girl hits puberty at the age of about 10-12 years.
• Menstruation stops temporarily when a girl gets pregnant.
