structure that warms, moistens, and filters air as it enters the respiratory tract and that houses the olfactory receptors for the sense of smell
central portion of the pharynx between the roof of the mouth and the upper edge of the epiglottis
lower part of the pharynx just below the oropharynx opening into the larynx and the esophagus
oval lymphatic tissues on each side of the pharynx that filter air to protect the body from bacterial invasion-also called palatine tonsils
small projection hanging from the back middle edge of the soft palate, named for its grape-like shape
lid-like structure that covers the larynx during swallowing to prevent food from entering the airway
windpipe; passageway for air from the larynx to the area of the carina where it splits into the right and left bronchus
two spongy organs, located in the thoracic cavity enclosed by the diaphragm and rib cage, responsible for respiration
membranes enclosing the lung (visceral pleura) and lining the thoracic cavity ( parietal pleura)
muscular partition that separated the thoracic cavity from the abdominal cavity and aids in respiration by moving up and down
partition that separates the thorax into two compartments (that contain the right and left lung) and encloses the heart, esophagus, trachea, and thymus gland
thin sheets of tissue that line the respiratory passages and secrete mucus, a viscid (sticky) fluid
hair-like processes from the surface of epithelial cells, such as those of the bronchi, that provide upward movement of mucus cell secretions
functional tissues of any organ such as the tissues of the bronchioles, alveoli, ducts, and sacs that perform respiration
pattern of breathing characterized by a gradual increase of depth and sometimes rate to a maximum level, followed by a decrease, resulting in apnea
popping sounds heard on auscultation of the lung when air enters diseased airways and alveoli- occurs in disorders such as bronchiectasis or atelectasis
high-pitched, musical sounds heard on auscultation of the lung as air flows through a narrowed airway- occurs in disorders such as asthma or emphysema
fluid filling of the spaces around the alveoli, eventually flooding into the alveoli
density on an x-ray representing solid material within the air spaces of the lungs, usually indicating inflammatory changes
panting, obsturctive pulmonary disease caused by a spasm of the bronchial tubes or by swelling of their mucous membrane, characterized by paroxysmal attacks of wheezing, dyspnea, and cough
obstructive pulmonary disease characterized by overexpansion of the alveoli with air, with destructive changes in their walls resulting in loss of lung elasticity and gas exchange
chronic obstructive pulmonary disease (COPD)
permanent, destructive pulmonary disorder that is a combination of chronic bronchitis and emphysema
inherited condition of exocrine gland malfunction causing secretion of abnormally thick, viscous mucus that obstructs passageways within the body, commonly affecting the lungs and digestive tract; mucus that obstructs the airways leads to infection, inflammation, and lung tissue damage
laryngotracheobronchitis (LTB)/ croup
inflammation of the upper airways with swellin that creates a funnel-shapped elongation of tissue causing a distinct " seal bark" cough
chronic restrictive pulmonary disease resulting from prolonged inhalation of fine dusts such as coal, asbestos, or silicone
inflammation in the lung caused by infection from bacteria, viruses, fungi, or parasites, or resulting from aspiration of chemicals
pneumonia caused by the Pneumocystis carinii organism- a common opportunictic infection sen in those with postive human immunodeficiency
pulmonary tuberculosis (TB)
disease caused by the presence of Mycobacterium tuberculosis in the lungs characterized by the formation of tubercles, inflammation, and necrotizing caseous lesions
periods of breathing cessation (10 seconds or more) that occur during sleep, often causing snoring
upper respiratory infectino (URI)
infectious disease of the upper respiratory tract involving the nasal passages, pharynx, and bronchi
arterial blood gases (ABGs)
analysis of arterial blood to determine the adequacy of lung function in the exchange of gases
