Body orifice

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 the sense of sight and crying.
 * 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.
