Body orifice
From Wikipedia, the free encyclopedia
A body orifice is an opening in the body of an animal. In a typical mammalian body such as the human body, the body orifices are:
- The nostrils, for breathing and the associated sense of smell.
- The eyes, for crying and the sense of sight.
- The mouth, for eating, breathing and vocalizations such as speech.
- The ear canals, for the sense of hearing.
- The anus, for defecation.
- The urethra, for urination, and in males, also for ejaculation.
- In females, the vagina, for sexual intercourse, menstruation and childbirth.
- The breast, especially in females for breastfeeding.
In other organisms with different body plans, there are other body orifices, such as the cloaca in reptiles, and the siphon in cephalopods.
