You’ve probably never sat down with a mirror and a flashlight to do a full inventory. Most people don't. But if you actually start counting, the math gets interesting. There’s a viral bit of trivia floating around about how a woman has 10 holes in her body, and honestly, it trips people up because we usually only think about the "obvious" ones.
We talk about mouths and ears. Maybe the nose. But the human body is basically a complex biological donut—or more accurately, a multi-holed topographic surface. When you get into the weeds of anatomy, specifically female anatomy, the number ten isn't just a random figure; it’s a specific anatomical count that distinguishes the female form from the male, which typically clocks in at nine.
It sounds weird. I know. But understanding this isn't just about winning a bar trivia night. It’s about health literacy. If you don't know what's supposed to be there, how do you know when something is wrong? Let’s break down the "ten holes" map and look at why each one actually matters for your daily survival.
Counting the Openings: The Anatomy of Ten
Most of us start the count at the head. It makes sense. You have two external auditory canals (your ears). Then you have two nostrils (nares). Add the mouth. That’s five. Simple.
Moving down, things get more specific to biological sex. This is where the phrase "a woman has 10 holes in her body" finds its footing. Men have a single opening for both reproduction and waste—the urethra at the tip of the penis. Women, however, have a separated system. In the pelvic region, a woman has three distinct openings: the urethra, the vaginal canal, and the anus.
Wait. That only gets us to eight.
The final two are the ones everyone forgets. They are the lacrimal puncta. These are the tiny, almost microscopic holes in the inner corners of your eyelids. If you’ve ever wondered how your tears drain into your nose (which is why your nose runs when you cry), it’s because of these two little drains. So, five on the face, three in the pelvic area, and two in the eyes. Ten.

The Evolutionary "Why" Behind the Pelvic Triple-Threat
Why did evolution decide women needed three holes down there while men got two? It’s mostly about hygiene and the sheer complexity of childbirth.
The urethra is strictly for urine. It’s short in women—only about 3 to 4 centimeters. This is actually a major medical downside. Because it’s so short and so close to the other openings, bacteria like E. coli have a very short commute to the bladder. That’s why women get UTIs (Urinary Tract Infections) significantly more often than men. Dr. Jane Miller, a urologist at the University of Washington, often points out that this proximity is the "anatomical curse" of female urology.
Then you have the vaginal canal. This is the "middle" hole. It’s a muscular, elastic passage that serves as the gateway for menstruation, intercourse, and birth. Unlike the urethra or the anus, the vagina is a self-cleaning ecosystem. It relies on a delicate balance of Lactobacillus bacteria to maintain an acidic pH. When people use harsh soaps or "douches" on this specific opening, they aren't helping. They’re essentially nuking a balanced forest and wondering why the weeds (yeast infections) start growing.
Finally, the anus. It’s the end of the digestive tract. Keeping this separate from the birth canal and the urinary tract is a biological necessity. Infection risk is the primary driver here.
The Head Openings: More Than Just Entrances
Let’s go back up to the face. The nostrils aren't just holes; they’re sophisticated climate control systems. The air you breathe is conditioned—warmed and humidified—before it ever hits your lungs.
And the ears? The external auditory canal is the only "hole" in the body that produces cerumen (earwax). This isn't "dirt." It’s a specialized coating designed to trap dust and repel water. When you use a Q-tip, you’re essentially jamming a ramrod into a delicate drainage system. Most audiologists will tell you the same thing: "Nothing smaller than your elbow should go in there."

The mouth is the big one. It’s the only opening that serves both the respiratory and digestive systems (via the oropharynx). This is a bit of a design flaw, honestly. It’s why humans are one of the few species that can easily choke on food. We traded a safer, separate airway for the ability to speak.
The "Hidden" Holes: Lacrimal Puncta
The lacrimal puncta are fascinating because they prove the body is a plumbing masterpiece. Every time you blink, your eyelids push tears across the surface of the eye toward these two tiny holes. From there, the fluid drains into the lacrimal sac and down the nasolacrimal duct.
If these holes get blocked, you end up with "epiphora," or constant tearing. Your eyes just overflow because the drain is clogged. It’s a reminder that even the smallest of the ten holes has a massive impact on your quality of life. Imagine trying to drive or work while your eyes are constantly "leaking" because a hole the size of a pinprick is obstructed.
Why This Math Matters for Your Health
Knowing that a woman has 10 holes in her body helps in identifying what is "normal" and what is an "abnormality." For instance, in some congenital conditions like an imperforate hymen, one of these openings (the vagina) may be partially or fully blocked, leading to severe pain during puberty.
There are also instances where "extra" holes appear, which are medically known as fistulas. An obstetric fistula is a devastating injury that can occur during prolonged, obstructed labor, creating a hole between the birth canal and the bladder or rectum. This results in chronic incontinence and is a major focus of global health initiatives by organizations like the UNFPA. Knowing the standard "ten" allows patients and providers to recognize when an eleventh, pathological hole has formed.
Myth-Busting the Count
Some people try to argue the count is higher. What about pores? Well, if we counted pores, we’d be in the millions. Pores are openings for sweat and sebum, but in anatomical terms, when we talk about "holes" or "orifices," we generally refer to the major openings that connect the internal organ systems to the outside world.

Others point to the belly button. Newsflash: the umbilicus is a scar, not a hole. Once the umbilical cord falls off and the area heals, it’s a closed depression. If you have a "hole" there, you likely have an umbilical hernia, which is something you should definitely see a doctor about.
Actionable Maintenance for the "Ten"
Taking care of ten different openings requires different strategies.
For the pelvic openings (the big three), the rule is simple: Wipe front to back. This prevents fecal bacteria from migrating toward the urethra and vagina. Also, skip the scented products. The vaginal opening is lined with mucosa, which is highly absorbent and sensitive. Chemicals that are fine on your arm skin can cause chemical dermatitis or disrupt the microbiome down there.
For the ear canals, stop cleaning them aggressively. If you have a blockage, use oil drops to soften the wax or see a professional.
For the lacrimal puncta (the eye holes), keep your eyelids clean. Blepharitis, or inflammation of the eyelids, can crust over these tiny drains. A warm compress once in a while does wonders for keeping the "eye plumbing" clear.
The Bottom Line on Body Map Literacy
Understanding the architecture of the human body isn't just for medical students. It’s for anyone who wants to live comfortably in their own skin. The fact that a woman has 10 holes in her body is a testament to the specialized, compartmentalized way the female body handles waste, reproduction, and sensory input.
Next Steps for Better Health:
- Audit your hygiene: Switch to pH-balanced, fragrance-free cleansers for the pelvic area to protect the vaginal microbiome.
- Hydrate for the "Drains": Your lacrimal puncta and urinary tract rely on fluid volume to flush out debris and bacteria effectively.
- Monitor the "Ten": If you notice unusual discharge, persistent blockage, or pain at any of these ten sites, consult a healthcare provider rather than attempting "at-home" fixes.
- Practice UTI Prevention: Given the proximity of the urethra to the other openings, always urinate after sexual activity to flush out any bacteria that may have moved toward the bladder.
