Document Summary
Conduct air into lungs while filtering, warming, and moistening it. Nose, pharynx, larynx, trachea, bronchi, bronchioles, terminal bronchioles. Exchange fresh o2 with waste co2 in the lungs. Lungs (respiratory bronchioles, alveolar ducts & sacs, alveoli) Externally composed of a bony framework (ethmoid bone) and. Internally composed of: a large nasal cavity (containing mucous membrane and muscle that aid in conducting, warming, filtering, and moistening incoming air), a vestibule, and a nasal septum. The nose allows for air to enter the r. s, and it warms, moistens, and filters inhaled air. Also is primary structure for olfactory epithelium (sense of smell). Sinuses help to lighten the skull and aid in warming, filtering, and moistening of the air entering the respiratory system. Also act as a resonating chamber for our voice. When we get a cold and the sinuses are plugged with mucous, that is why our voices sound odd. Tube of muscle that connects to the: nasal cavity and mouth superiorly, and.
