External respiration (breathing): Oxygen passes from lungs to blood (capillaries) and carbon dioxide passes from capillaries back into lungs to be expelled. Internal respiration: The body cells take on oxygen from the blood and give back carbon dioxide, which is transported back to the lungs.

All rights reserved. 5-4 Organs of the Respiratory System nose: lined with mucous membrane and fine hairs; acts as a filter to moisten and warm the entering air pharynx (throat): serves as a food and air passageway adenoid: lymphoid tissue located behind the nasal cavity tonsils: lymphoid tissue located behind the mouth Copyright © 2009, 2006 by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved. 5-5 Organs of the Respiratory System (cont’d.) larynx (voice box): location of the vocal cords epiglottis: flap of cartilage that automatically covers the opening of the larynx during swallowing and keeps food from entering the larynx trachea: passageway for air to the bronchi Copyright © 2009, 2006 by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved. 5-6 Organs of the Respiratory System (cont’d.) bronchus: one of two branches from the trachea, which conducts air into the lungs, where it divides and subdivides (referred to as a bronchial tree). bronchioles: smallest subdivision of the bronchial tree alveoli: air sacs at the end of the bronchioles; oxygen and carbon dioxide are exchanged through alveolar walls and capillaries Copyright © 2009, 2006 by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved. 5-7 Organs of the Respiratory System (cont’d.) lungs: 2 sponge-like organs in the thoracic cavity (right lung has 3 lobes; left lung has 2 lobes) pleura: serous membrane covering each lung and lining the thoracic cavity diaphragm: muscular partition that separates the thoracic cavity from the abdominal cavity; aids in breathing mediastinum: space between the lungs Copyright © 2009, 2006 by Mosby, Inc., an affiliate of Elsevier Inc.

He had a history of asthma since the age of 12 years. A chest radiograph was negative for pneumonia. Arterial blood gases showed hypoxemia but no hypercapnia. Pulmonary function tests disclosed bronchoconstriction, which was corrected by a bronchodilator. A nebulizer was prescribed for treatment. The asthma attack was probably precipitated by an episode of bronchitis. Copyright © 2009, 2006 by Mosby, Inc., an affiliate of Elsevier Inc. All rights reserved. 5-42
