The vaginal orifice is the external opening of the vagina, which is part of the female reproductive system. It is located between the urethra and the anus and serves as the entry point for menstrual fluid, sexual intercourse, and childbirth. The vaginal orifice is surrounded by the vulva, which includes other structures such as the labia and the clitoris. The size and shape of the vaginal orifice can vary among individuals and may change due to factors like age, hormonal changes, or childbirth. It is an important part of female anatomy, playing a role in both reproductive health and sexual function.
