Menstruation

Menstruation is a name given to a periodical biological phenomenon of discharge of blood through vagina. The ovaries of a girl between the ages 10-15 years start producing a mature egg or ovum each month. The egg travels down the fallopian tube, which connects the ovary to the womb. When the egg reaches the womb, the lining becomes thick with blood and fluid. This happens so that if the egg is fertilized, it can grow and develop in the lining to produce a baby. If the egg does not meet with sperm from a male and is not fertilized, it dissolves. The thickened lining sloughs off and forms menstrual blood flow, which passes out of the body through the vagina.
