Term | Definition |
Respiratory System Organs | nose, pharynx, larynx, trachea, bronchi, lungs |
Respiration | exchange of oxygen and carbon dioxide between atmosphere, blood and cells |
Respiratory Functions | carbon dioxide out and oxygen in, protects the surface of the lungs, trachea from dehydration, temp changes and pathogens; produces sounds needed for speech, aids the sense of smell |
Membranes and Cavities | Thoracic and Abdominal Cavities; separated by the diaphragm; the walls are covered by parietal pleura; the organs' surface is covered with visceral pleura |
Thoracic Cavity | most of the respiratory organs are located here; left and right lung and surrounding pleura on each side of cavity; contains the mediastinum |
Mediastinum | the area between the lungs in the chest cavity that contains the heart, aorta, trachea, esophagus and bronchi |
Visceral Pleura | covers the surface of organs, such as the lungs; portion of the pleura that is closest to the internal organs |
Parietal Pleura | covers the walls of the respiratory cavities; portion of the pleura that is closest to the ribs |
External Nares | openings into the nose; choana(e): link from external nares to nasopharynx |
Internal Nares | connect nose and pharynx; functions: warm and moisturize air, smell, speech tone |
Olfactory Receptors | located in the Superior Meatus |
Turbinate Bones | Superior, Middle and Inferior Meatus |
The nasal and oral cavity are separated by | the bony hard palate and the soft palate made of cartilage |
Nasal Cavity is divided at | the midline by nasal septum; made up of ethmoid, vomer bone and septal cartilage |
Sinuses | empty spaces in the nasal cavity, lighten the skull, act as resonance chamber for speech, produce mucus |
Paranasal Sinuses | Interosseous spaces named after the bones that create them; maxillary, frontal, sphenoid and ethmoid; assist in respiration by warming and moistening inspired air |
Nasal Chonchae | curled bone shelves that force air flow over the largest surface area of cilia possible |

Cilia | hairlike projections on the mucous membranes, sweep dirt and foreign material toward the throat for elimination |
Bronchi | are formed by the division of the trachea; continue to subdivide: primary bronchi to secondary bronchi to tertiary bronchi to bronchioles |
Lung | along with heart occupies most of thoracic cavity; apex of lung is near the clavicle, base rests on diaphragm; each lung is divided into lobes; RL has 3 lobes; LL has 2 lobes |
Pleural Membrane | encloses and protects lungs; Parietal Pleura (outer), Visceral Pleura (inner), Pleural Cavity (btwn pleura, prevents friction) |

External Respiration (breathing) | exchange gases between lungs and blood |
Internal Respiration | exchange of gases between blood and body cells |
Intercostal Nerves | arise from T1-T11 spinal nerve roots to innervate internal and external intercostal muscles |
Phrenic Nerve | bilateral mixed nerve that arises primarily from C3-C5; "keeps diaphragm alive |
Cellular Respiration | = respiration proper |
Croup | a common in young children; tends to occur in fall and winter; barking cough; raspy, hoarse voice; a harsh, crowing noise when breathing in |
Laryngitis | inflammation of voice box (larynx) from overuse, irritation or infection; dysphonia (hoarseness), aphonia, cough, difficulty swallowing |
Pertussis (whooping cough) | highly contagious respiratory disease, caused by bacterium Bordetella pertussis; known for uncontrollable, violent coughing; can be deadly in less than 1 year of age |
Pharyngitis | usually caused by virus, also can be bacteria infection, strep throat-group A streptococcus, sore throat is typical |
Sinusitis | inflammation of the sinuses, thick nasal mucus, plugged nose and pain in the face, can be caused by infection, allergies, air pollution or structural problems in the nose; treatment includes abx, decongestants, analgesics |
Tonsillitis | inflammation of tonsils, rapid onset, type of pharyngitis; sore throat, fever, enlarged tonsils, trouble swallowing, large lymph nodes; peritonsillar abscess; tonsillectomy |
Restrictive Lung Disease | inhale; restrict lung expansion, resulting in decreased lung volume, an increased work of breathing and inadequate ventilation and/or oxygenation |
Obstructive Lung Disease | exhale; category of respiratory disease characterized by airway obstruction; asthma, bronchiectasis, bronchitis and COPD |
Asthma | severe attack of difficult breathing accompanied by wheezing caused by a spasm of the bronchial tubes or by swelling of the mucous membrane |
COPD (chronic obstructive pulmonary disease) | includes chronic bronchitis and emphysema, causes serious long-term disability and early death, main cause is smoking |
COPD Symptoms | chronic cough, SOB, frequent respiratory infections, blueness of lips or fingernails beds, fatigue, producing a lot of mucus, wheezing |
Exacerbation | an acute change in a patient's baseline dyspnea, cough, or sputum that is beyond normal variability and that is sufficient to warrant a change in therapy |
COPD Diagnosis | Spirometry, CXR, Arterial Blood Gas (ABG) |
Spirometry | blow air into a mouthpiece and tubing attached to a small machine. |
CXR | hyperinflation |
Arterial Blood Gas (ABG) | measures the oxygen level in your blood |
COPD Treatment | oxygen and ventilation, Bronchodilators: inhalers, Corticosteroids, Antibiotics |
Emphysema | involves gradual damage of lung tissue, specifically thinning and destruction of the alveoli or air sacs |
Chronic Bronchitis | inflammation and swelling of the lining of the airways, leading to narrowing and obstruction |
Empyema | known as pyothorax or purulent pleuritis, is an accumulation of pus in the pleural cavity |

Pulmonary Embolism Diagnosis and Treatment | Blood test, Doppler for leg DVT, CT; anticoagulation, insertion of IVC filter |
Cor Pulmonale | condition that causes the right side of the heart to fail; long-term high blood pressure in the arteries of the lung and right ventricle can lead to this |
