Which term refers to the openings that connect the nasal cavity to the outside environment?

Explanation:
Nostrils are the openings that connect the nasal cavity to the outside environment. They sit on the face and allow air to enter and exit into the nasal passages, where it is filtered, warmed, and humidified before moving deeper into the respiratory tract. The term nasal passage refers to the internal channel inside the nose, not the external openings. The mouth can also let air in, but it’s not the opening that connects the nasal cavity to the outside. The larynx is the voice box lower in the airway, not an exterior nasal opening.
