Women have three openings in the area between their legs: the urethral opening (where urine comes out), the vaginal opening, and the anus. All three are separate, each with its own function. This is one of the most commonly searched anatomy questions online, and it’s a genuinely useful one. A study that asked participants to identify female genital structures found that only 9% could correctly label all of them on a diagram.
Where the Three Openings Are
The three openings are arranged in a line from front to back. The urethral opening sits closest to the front of the body, just below the clitoris. The vaginal opening is directly behind it. And the anus is farther back, separated from the vaginal opening by a small patch of skin called the perineum. That patch of skin averages about 3.7 centimeters (roughly 1.5 inches) in length.
The first two openings, the urethra and the vagina, are both located within an area called the vulvar vestibule. This is the smooth-skinned area nestled between the inner lips (labia minora). The anus sits behind and outside this area entirely. It belongs to the digestive system, not the reproductive or urinary system, but it’s part of the same general region people are asking about.
The Urethral Opening
The urethral opening is small and can be hard to spot. Its only job is to let urine pass from the bladder out of the body. The female urethra is short, only about 3 to 4 centimeters long, and it sits very close to the vaginal opening. Because of that close proximity, bacteria can sometimes travel from one area to the other, which is one reason urinary tract infections are more common in women than in men.
On either side of the urethral opening are two tiny glands sometimes called the paraurethral glands. Their openings are nearly impossible to see with the naked eye. They produce small amounts of fluid, but they’re not something most people would ever notice or need to think about.
The Vaginal Opening
The vaginal opening is larger and sits just behind the urethral opening. It’s the entrance to the vagina, a flexible muscular canal inside the body. This single opening serves multiple functions: menstrual blood exits through it, it’s where penetrative sex occurs, and it’s the passage a baby travels through during vaginal childbirth.
The vaginal opening is partially surrounded by a thin piece of tissue called the hymen. In most people, the hymen is ring-shaped or crescent-shaped and leaves most of the opening uncovered. It doesn’t seal the vagina shut. In rare cases, a hymen can cover the entire opening (called an imperforate hymen), which typically needs medical attention during puberty so menstrual blood can flow normally. Other variations include hymens with many small holes or an extra band of tissue across the middle. All of these are natural variations, not abnormalities.
Near the vaginal opening, there are also two small glands (one on each side) that produce lubricating fluid during arousal. Like the glands near the urethra, their openings are tiny and not easily visible.
The Anus
The anus is the rearmost opening and is part of the digestive tract, not the reproductive or urinary system. It’s the exit point for the large intestine, controlled by a ring of muscle called the sphincter that allows you to hold and release bowel movements. Both men and women have an anus, so it’s not unique to female anatomy, but it’s relevant here because people asking this question are typically trying to understand the full layout of the area.
Vulva vs. Vagina
One reason this topic causes confusion is that people often use “vagina” to refer to everything between a woman’s legs. The vagina is actually just the internal canal and its opening. The correct word for the entire external area, including the inner and outer lips, the clitoris, the urethral opening, and the vaginal opening, is the vulva. The vaginal opening is located inside the vulva, but the vulva includes much more than the vagina.
This mix-up is extremely common. Even in everyday conversation and media, “vagina” gets used as a catch-all term. Knowing the distinction helps when communicating with a doctor, understanding your own body, or teaching someone else about anatomy. The three openings are part of two different body systems (urinary and digestive) plus the reproductive system, all housed in the same compact region of the pelvis, which is why it can feel confusing until you see how they’re arranged.
