(1) What is the purpose of the respiratory system? (2) Describe the path of air from the nose to the lungs. (3) Which organs are part of the upper respiratory tract and what is the function of each organ? (4) Several organs have connections with the pharynx. What are they? (5) What two pathways cross in the pharynx? Why is it correct to say they cross? (6) What organs are part of the lower respiratory tract? What are the the functions of each organ? (7) Which organ of the respiratory tract functions in gas exchange? (8) What are some common infections and disorders of the upper respiratory tract? (9) What are some common infections and disorders of the lower respiratory tract? (10) What are the three respiratory disorders commonly associated with smoking tobacco?
 * ensures that oxygen enters the body and carbon dioxide leaves the body during inhalation and exhalation
 * when the air moves along the airways it is cleaned, warmed, and moistened
 * as the air moves it cools and loses moisture inside the trachea
 * the air goes through the nose, then pharynx, larynx, trachea, then the lungs
 * nares-passage of air into nasal cavities
 * Nasal cavities- filter, warm, and moisten the air
 * pharynx- connection to surrounding regions
 * glottis-passage of air into larynx
 * larynx-produces sound
 * nasopharynx
 * oropharynx
 * laryngopharynx
 * tonsils
 * air passage and the food passage
 * because the larynx(which receives air) is ventral to the esophagus (which receives the food)
 * Trachea-passage of air to bronchi
 * Bronchi-passage of air to the lungs
 * bronchioles-passage of air to each alveolus
 * lungs-contain alveoli and blood vessels
 * lungs
 * strep throat
 * sinusitis
 * otitis media
 * Tonsillitis
 * Laryngitis
 * acute bronchitis
 * Pneumonia
 * Pulmonary tuberculosis
 * Pulmonary Fibrosis
 * Chronic Bronchitis
 * Emphysema
 * asthma
