Women have three openings in the area between their legs: the urethral opening (where urine comes out), the vaginal opening, and the anus. These three holes are close together but completely separate, each connected to its own system in the body. A lot of people grow up thinking there are only two, so if this is new information, you’re far from alone.
Where Each Opening Is Located
All 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. It’s tiny and can be hard to spot. Right below it is the vaginal opening, which is noticeably larger. Both of these openings are located within the vulva, which is the name for all the external anatomy between a woman’s legs. Farther back, between the buttocks, is the anus.
People often use “vagina” to refer to everything down there, but the vagina is actually just one specific structure: a flexible, muscular canal inside the body. The vulva is the correct term for the outer area that includes the labia, clitoris, urethral opening, and vaginal opening.
The Urethral Opening
The urethral opening is the exit point for urine. It connects to the urethra, a short tube that runs from the bladder to the outside of the body. In women, this tube is much shorter than in men, which is one reason urinary tract infections are more common in women. Because the opening is so small and tucked between the clitoris and vaginal opening, many women have never visually identified it on their own body. It serves one purpose only: letting urine pass out of the body.
The Vaginal Opening
The vaginal opening sits just below the urethral opening. It leads to the vaginal canal, which connects to the uterus through the cervix. This single opening serves several functions. Menstrual blood exits the body through it during a period. It’s the opening involved in penetrative sex, and the vaginal walls expand and produce lubrication during arousal. During childbirth, a baby passes through the vaginal canal and out this opening, which is why the vagina is sometimes called the birth canal.
The vaginal opening may be partially covered by a thin membrane called the hymen, especially in younger women. The hymen varies dramatically in shape and size from person to person and often wears away naturally over time from physical activity, tampon use, or sex.
The Anus
The anus is the third opening, located farthest back. It’s the end point of the digestive tract. A ring of muscle called the anal sphincter keeps it closed until a bowel movement, when the muscle relaxes to allow stool to pass. Though it’s in the same general region as the other two openings, the anus is part of an entirely different body system and is not connected to the reproductive or urinary organs in any way.
Why the Confusion Is So Common
Many people believe women have only two openings: one for urination and sex, and one for bowel movements. The confusion usually comes from the fact that the urethral opening and vaginal opening are very close together, both hidden within the folds of the labia. Without a mirror and good lighting, they’re difficult to distinguish. Sex education in many schools glosses over this level of detail, and the habit of using “vagina” to mean everything between a woman’s legs makes the anatomy harder to picture accurately.
Knowing these are three separate openings matters for practical reasons. Understanding that urine comes from its own dedicated opening (not the vagina) helps make sense of why you can urinate with a tampon in, for example. It also helps with recognizing symptoms: burning during urination points to the urinary tract, while unusual discharge involves the vagina. These are different systems with different causes and treatments.
Internal Openings Worth Knowing About
Beyond the three external openings, the cervix acts as an important internal gateway. It sits at the top of the vaginal canal and connects the vagina to the uterus. The cervix has two small openings of its own: one that faces the vagina and one that opens into the uterus. These openings are narrow enough that a tampon or menstrual cup cannot pass through them into the uterus. During labor, the cervix dilates to allow a baby through.
Total Body Openings
If you’re curious about the whole body and not just the pelvic area, women have more openings than the three described above. Counting all visible orifices: two nostrils, the mouth, two ear canals, two eyes (each with tiny tear ducts that drain into the nose), the urethral opening, the vaginal opening, and the anus. That brings the total to around nine or ten, depending on whether you count each tear duct separately. The three pelvic openings are just the ones most often asked about, and the ones most frequently misunderstood.
