 | | Menstruation is a normal, natural shedding process of the uterine lining that occurs monthly in all healthy adult women after puberty. |
 | | The parts of the body involved in the menstrual cycle include the brain, uterus, cervix, ovaries, fallopian tubes, and vagina. |
 | | If the egg is not fertilized by a sperm, the thickened lining of the uterus consisting of blood-filled uterine tissue is shed. |
