Question

How does mensuration occur??

Answer 1

hey dude

ur answer is here...!!!!!

After the egg has left the ovary, it travels through the Fallopian tube to the uterus. Hormone levels rise and help prepare the uterine lining for pregnancy. ... If the egg is not fertilized, it will break apart. Then, hormone levels drop, and the thickened lining of the uterus is shed during the menstrual period.

thanks....!
