define mensuration cycle.

Answer:Menstruation is the process of the shedding of the uterine lining on a regular monthly basis. It begins at puberty and is the reproductive cycle of the female body. Every month, the uterus prepares itself to receive a fertilised egg. Therefore, the inner lining of the uterus becomes thick and is supplied with blood to nourish the embryo. If the egg is not fertilised, then the lining of the uterus breaks down and gets Released in the form of blood through the vagina. This lasts for about two to eight days. This cycle occurs every month and is known as the menstrual cycle.
At the onset of puberty, the ovaries in girls starts to mature. Every month one ovum gets matured and then gets released by the ovaries. This procedure happens once in 28 to 30 days approximately. At this time of month the uterine wall becomes thick to receive the mature egg. If the egg gets fertilised and begins to develop it leads to pregnancy. But if fertilisation does not occur then the released egg and thick lining of uterus along with blood gets shed off through the vagina in females. This leads to bleeding in women at a specific period of month (once in about 28-30 days) and is called menstruation.
