Document Summary

Ventilation: movement of air into and out of lungs. External respiration: gas exchange between air in lings and blood, transport of oxygen and carbon dioxide in the blood. Internal respiration: gas exchange between the blood tissues. Regulation of blood ph: altered by changing blood carbon dioxide levels. Voice production: movement of air past vocal folds makes sound and speech. Olfaction: smell occurs with airborne molecules drawn into nasal cavity. Protection: against microorganisms by preventing entry and removing them. In the airways upper tract and lower tract. This conserves a lot of water, it does not matter in climates like vancouver, but in drier climates it can make a big differences.
