The human body has several types of holes or openings, which can be categorized mainly into natural body orifices and smaller openings like pores and hair follicles.
Major Natural Body Holes (Through-Holes)
There are seven main through-holes in the human body that connect internal cavities to the outside world:
- Mouth
- Two nostrils (left and right)
- Two ears (left and right)
- Anus
- Urethra (in males and females)
These seven holes are considered "through-holes" because they have an entrance and an exit or connect to internal cavities that open externally
. In females, the vagina is an additional external opening, making it eight through-holes for women
Other Openings and Blind Holes
Besides these, the body has many other openings such as:
- Hair follicles (about 5 million across the body)
- Sweat gland ducts
- Pores on the skin
- Sinuses (which are blind holes, meaning they do not connect through the body)
- Nipples (which are openings but not through-holes)
These smaller openings are numerous and vary individually but are generally considered blind holes because they do not pass completely through the body like the main orifices
Summary
- 7 main through-holes in males: mouth, two nostrils, two ears, anus, urethra
- 8 main through-holes in females: same as males plus vagina
- Millions of smaller holes: hair follicles, sweat ducts, pores (blind holes)
Thus, the human body can be described as having seven to eight major holes, depending on sex, plus millions of tiny pores and follicles
