What is menstruation?Explain.

Answer 1

Menstruation (men-STRAY-shuhn) is a woman's monthly bleeding. When you menstruate, your body sheds the lining of theuterus(womb). Menstrual blood flows from the uterus through the small opening in thecervixand passes out of the body through thevagina(see how the menstrual cycle works below). Most menstrual periods last from 3 to 5 days.

Answer 2

menstruation only happens in females who reached puberty.puberty is the first menstruation. ovaries release,females eggs,a.k.a ova one by one.means if,in a one period an egg is released by left ovary then the next one is released by the right ovary.this process of releasing ova is called ovulation.the time period taked to release another egg appr. is 28days. when ovary is released and if there are no sperms(male eggs) to fertilize it,the egg n the othr parts breaks down and comes out of the vagina with blood.this is called menstruation.normally it takes 3-5days to finish menstruation. hope i helped u :-)
