The respiratory system is made of body parts that are in charge of your breathing. It includes your nose and nasal cavity. You inhale air though your nose. As you inhale, small specks of dirt are trapped by many tiny hairs in your nose. This cleans the air. The hairs stop the dirt from going further in your body. The moist inside surface in your nose traps even smaller pieces of dirt. The nasal cavity, the air passage behind the nose, plays an important role in breathing. The nasal cavity is divided into a right and left passageway. The tissue that covers the wall of your nasal cavity contains many blood vessels. Heat from the blood in the vessels helps warm the air as you breath. Moisture is added to the air you breath by special cells in the walls of the nasal cavity. The air is warmed and moistened before it reaches your lungs.

Inhaled air is moistened, warmed, and cleansed by the nasal epithelium (the tissue that lines the nasal cavity), which covers the turbinate bones (conchae) in the nasal cavity. The nasal epithelium has increased blood flow that helps to warm the inhaled air, but also facilitates nosebleeds in some people.
