Hi Dude




The changes that occur in uterus .

I) When egg is fertilised

The uterus has three layers namely Edometrium,Perimetrium and myometrium (From outside)

The embryo is implanted in endometrium.As the implantation occurs the linings of uterus become thick.


II) When egg is not fertilised


The endometrium bears certain muscles which starts to break and come out through vagina as menstruation flow.
