MA+Respitory+System

Respiratory System (1) What is the purpose of the respiratory system? The purpose of the respiratory system is to make sure oxygen enters and carbon dioxide leaves the body.

(2) Describe the path of air from the nose to the lungs. The nose is where air is filtered and warmed and from there the air goes down the pharynx, also the same place food goes down. Air then goes down the trachea which then leads 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? The pharynx is connected with esophagus, the larynx, glottis, tonsils, and the nasal cavity. (5) What two pathways cross in the pharynx? Why is it correct to say they cross? The larynx and pharynx. The larynx is usually open and the esophagus is usually closed in less you swallow food. (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? The lungs. (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? 1) Chronic brichotis: airways are filled with mucus 2) Emphysema: alveoli and their walls are permanently damaged 3) lung cancer: tumors in the lungs
 * Nasal Cavity: where air is filtered, warmed, and moistened.
 * Pharynx: passageway for food and air
 * Glottis: leads to the larynx
 * Larynx: helps us take...voice box
 * Trachea: The air goes through the passageway to get in the lungs
 * Bronchus: passage way to the lungs
 * Bronchioles: passage to alveoli
 * Lung: where "gas exchange occurs"
 * Diaphram: helps with breathing, expands and extracts to allow air in and out
 * Sinusitis: When nasal congestion blocks the sinus passageways
 * Otitis Media: When a nasal infection moves to the ear.
 * Tonsillitis: When tonsils swell and are enlarged.
 * Laryngitis: infection of the larynx
 * Acute bronchitis: infection of the bronchi
 * Pneumonia: Viral and/or bacterial infection of the lungs
 * Pulmonary Tuberculosis: An infection of bacterium in the lungs
 * Pulmanary fibrosis: when fiber glass or other similiar things are inhaled and connective tissue builds up in the lungs.
 * Asthma: disease of the bronchi
