Question

WHY DO WE HAVE PERIODS EXPLAIN IT

Answer 1

A period happens because of changes in hormones in the body. Hormones give messages to the body. These hormones cause the lining of the uterus (or womb) to build up. This gets the uterus ready for an egg (from the mom) and sperm (from the dad) to attach and grow into a baby.Menstrual blood comes out which is partly blood and partly tissue from the inside of the uterus—flows from the uterus through the cervix and out of the body through the vagina.
