The labia are the external folds of skin that surround the vagina in females. They are part of the vulva, which includes other structures such as the clitoris and the urethra. The labia are divided into two main parts: the labia majora, which are the larger outer folds, and the labia minora, the smaller inner folds. Their primary functions include protecting the internal reproductive organs and providing sensitivity. Labia come in various shapes, sizes, and colors, and their appearance can differ significantly among individuals. They play a role in sexual arousal and can also be involved in the process of childbirth. Understanding the anatomy of the labia is important for sexual health and education.
