उत्तर
menstruation
Explanation -
With the onset of reproductive phase, uterine lining of human females becomes thick and spongy to nourish the embryo if fertilisation had taken place. In the absence of fertilisation, this lining is not needed any longer. So, the lining slowly breaks and comes out through the vagina as blood and mucous. This cycle takes place roughly every month and is known as menstruation.
