Body orifice

From Wacklepedia - The Free Encyclopedia

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 mouth, for eating and vocalizations such as speech
• the ear canals, for the sense of hearing
• the anus, for defecation
• the urethra, for urination (and in males, for ejaculation)
• in females, the vagina, for sexual intercourse and childbirth

In other organisms with different body plans, there are other body orifices, such as the cloaca in reptiles, and the siphon in cephalopods.
