Cilia Hairlike projections on the mucous membranes that sweep dirt and foreign material toward the throat for elimination
Pharynx Throat; An airway that connects the mouth and nose to the larynx
Pharynx (3 sections) Nasopharynx / Oropharynx / Laryngopharynx
Epiglottis A small flap of cartilage that covers the opening of the larynx so that food cannot enter
Larynx Voice box; contains structures that make vocal sounds possible (vocal cords)
Adenoids Lymphatic tissue forming a prominence on the wall of the recess of the nasopharynx
Alveoli Air cells of the lungs; known as pulmonary parenchyma (FUNCTIONAL UNIT OF THE LUNGS)
Bronchi Two main branches leading from the trachea to the lungs, providing the passageway for air movement
Bronchiole One of the smaller subdivisions of the bronchial tubes
Epiglottis Covers the entrance of the larynx when you swallow
Palatine Tonsils Lymphatic tissue located in the depression of the mucous membrane of fauces and the pharynx
Pleura Double-folded membrane that lines the thoracic cavity
Trachea Windpipe; Cylinder-shaped tube lined with rings of cartilage (to keep it open)

Bradypnea Abnormally slow breathing
Cyanosis Bluish, grayish, slatelike, or dark purple discoloration of the skin due to reduced hemoglobin in the blood
Dyspnea Air hunger resulting in labored or DIFFICULT BREATHING
Epistaxis Nosebleed
Hypoxia Deficiency of oxygen
Rhinorrhea Thin, watery discharge from the nose
Sneeze Expel air forcefully
Tachypnea Abnormal fast breathing
Wheeze A whistling sound resulting from narrowing of the lumen of a respiratory passageway
Scarlet Fever Infection that goes untreated; In adults- Scabies
Croup Chilhood disease characterized by a barking cough, suffocative and difficult breathing, stridor, and laryngeal spasm

Chronic long term
Acute right now; short term
Rhinitis Inflammation of the mucous membranes of the nose
Sinusitis Inflammation of a sinus

Exercise induced asthma can be outgrown; NOT chronic
Allergy induced asthma only cured when allergy is removed; can be acute/ chronic
Chronic asthma long term asthma
Bronchitis Inflammation of the mucous membrane of the bronchial tubes
Bronchogenic carcinoma chronic lung cancer
Emphysema a chronic obstruction (increase in airway resistance) to the inflow and outflow of air from the lungs; major cause: cigarette smoking
Pleural Effusion Accumilation of fluid in the pleural space; compresses the lung
Pleuritis (pleurisy) Inflammation of both the visceral pleura (organ side) and parietal pleura(outer side)
Pneumonia Inflammation of the lungs caused primarily by bacteria, viruses, and chemical irritants
Pneumothorax collapsed lung; a collection of air or gas in the pleural cavity
Pulmonary Embolism The obstruction of one or more pulmonary arteries by a thrombus that dislodges from another location
SIDS sudden infant death syndrome
Tuberculosis An infectous disease caused by the tubercle bacillus (mycobacterium tuberculosis); spread by droplet infection (sneezing/ coughing)
Asbestosis (5 pts) Lung disease resulting from inhalation of asbestos particles
