Document Summary

Respiration (ventilation, gas exchange b/w lungs & blood & blood & tissues o2 & co2 transport) Olfaction: general anatomy of the respiratory system. Passageway for air; cleans, humidifies, warms air; contains olfactory epithelium; helps determine voice sound: pharynx. Allows movement of air from the nose/mouth to larynx: larynx. Passageway for air b/w pharynx & trachea. Prevents swallowed material from entering lower respiratory tract & regulates the passage of air into and out of the lower respiratory tract. Vocal folds are primary source of sound production. Wide hollow tube that connects larynx to bronchi: lungs. Bronchi & bronchioles passageway for air. Alveoli- site of gas exchange b/w air and blood. Conducting zone extends from nose to bronchioles; air movement. Respiratory zone site of gas exchange b/w air & blood; in lungs: explain how the contraction of respiratory muscles changes thoracic volume during both quiet & labored (exercise) breathing.
