External orifices

- The nostrils, for breathing and the associated sense of smell
- 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 ejaculation
- In females, the vagina, for menstruation, sexual intercourse and childbirth
Other animals may have some other body orifices:
- cloaca, in birds, reptiles, amphibians, and some other animals
- siphon in mollusk, arthropods, and some other animals
