Q

Describe the loaction, structure, & functions of the vagina.

Q

Vulva (Structures & Functions)

A
  • Structures
    • The labia majora, mons pubis, labia minora, clitoris,bulb of vestibule, vulval vestibule, greater and lesser vestibular glands, and the opening of the vagina (introitus).
  • Functions
    1. It protects women’s sexual organs and the urinary opening from trauma and infection.​
    2. It is vital for women’s sexual

response. The clitoris is the main organ of sexual arousal and orgasm in most women.
3. The vulva and the perineum stretch to accommodate childbirth.
