Body orifice

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