Anatomy
| Structure | Function |
|---|---|
| nasal cavity (hollow space within nose) | conducts air to pharynx; mucous lining filters, warms, and moistens air |
| sinuses (hollow space in bones of the skull) | reduces weight of the skull; serve as resonant chambers; spaces for conditioning of air |
| larynx ( enlargement at the top of the trachea) | passageway for air; houses vocal cords |
| trachea (rigid tube that connects larynx to bronchial tree) | passageway for air; mucous lining filters air |
| bronchial tree (branched tubes that lead from the trachea to the alveoli) | conducts air from the trachea to the alveoli; mucous lining filters air |
| lungs (soft, cone-shaped organs that occupy most of the thoracic cavity | contain the air passages, alveoli, blood vessels, and other tissues of the lower respiratory tract |
