The vagina is a muscular tube that connects the external genitals to the uterus in the female reproductive system. It serves as the birth canal during childbirth and also plays a role in sexual intercourse and menstrual flow.
The uterus is a pear-shaped organ located within the female pelvis, where fetal development occurs.
The cervix is the lower, narrow part of the uterus that opens into the vagina and acts as a gateway between the uterus and vagina.
Menstruation is the monthly shedding of the uterine lining when pregnancy does not occur, resulting in bleeding through the vagina
