vagina
Sign in to saveThe vagina (: vaginas or vaginae) is the elastic, muscular reproductive organ of the female genital tract through which mammals copulate and give birth. In humans, it extends from the vulval vestibule to the cervix (neck of the uterus). The vaginal introitus is normally partly covered by a thin layer of mucosal tissue called the hymen. The vagina also channels menstrual flow, which occurs in humans and closely related primates as part of the menstrual cycle.
AI overview
The vagina is an elastic, muscular reproductive organ that extends from the vulva to the cervix and plays several important roles in female biology. It serves as the passage through which sexual intercourse occurs, babies are born, menstrual flow exits the body, and it is partly covered by a thin tissue called the hymen.

The vagina (: vaginas or vaginae) is the elastic, muscular reproductive organ of the female genital tract through which mammals copulate and give birth. In humans, it extends from the vulval vestibule to the cervix (neck of the uterus). The vaginal introitus is normally partly covered by a thin layer of mucosal tissue called the hymen. The vagina also channels menstrual flow, which occurs in humans and closely related primates as part of the menstrual cycle.
During sexual intercourse, the vaginal walls produce vaginal lubrication and create friction which stimulates the penis toward ejaculation, enabling fertilization. Along with pleasure and bonding, sexual activity can cause sexually transmitted infections (STIs), which can be prevented by safe sex practices. Other health issues may also affect the human vagina.
