• Menstrual blood is shed from the uterus every month through the cervix and vagina.
• During the menstrual cycle, the uterus builds up a lining called the endometrium in preparation for pregnancy.
• If fertilization does not occur, the hormones that maintain the uterine lining decrease, causing it to shed as menstrual blood.
• The blood flows out through the cervix, which is the lower part of the uterus, and then passes through the vagina.
• Menstruation typically lasts for several days and is a natural part of a woman’s reproductive cycle.
• It is important to use appropriate hygiene products, such as sanitary pads or tampons, to manage menstrual blood flow.
