검증된 단계별 안내1
Understand the menstrual cycle: The menstrual cycle is a monthly process that prepares the female body for pregnancy. It involves the thickening of the endometrium (the lining of the uterus) to support a potential pregnancy.
Identify the role of the endometrium: The endometrium is the inner lining of the uterus that thickens during the menstrual cycle in preparation for a fertilized egg to implant.
Recognize what happens if pregnancy does not occur: If the egg is not fertilized, the thickened endometrium is not needed and will be shed from the body.
Define menstruation: Menstruation is the process by which the endometrium is shed from the uterus and exits the body through the vagina, resulting in menstrual bleeding.
Conclude the correct answer: Therefore, menstruation results in the discharge of the endometrium, not the follicle, corpus luteum, surface cells from the vagina, or blood from the outer surface of the uterus.
