Which of the following best describes the role of labia majora?

The role of the labia majora is primarily to protect the reproductive organs. These are the larger, outer folds of skin that form part of the vulva, which is the external female genitalia. The labia majora encase and safeguard the more sensitive structures of the vulva, including the labia minora, clitoris, and vaginal opening, from environmental factors and potential injury. Their presence helps to maintain the integrity of the internal reproductive organs by providing a barrier and shielding them from bacteria and pathogens.

While elements like stimulating sexual arousal or facilitating childbirth are important in the context of female reproductive health, those functions are primarily associated with other structures, such as the clitoris or the vagina. Additionally, menstrual flow is managed by the uterus and vagina, not the labia majora. Thus, the primary protective function underscores why this is the best description of the labia majora’s role.
