| Inflammation of breathing passages caused by allergens | asthma |
| Inflammation of the trachea and bronchi | bronchitis |
| "floppy lung" | emphysema |
| chronic disease which is a combination of asthma, emphysema and chronic bronchitis | chronic obstructive pulmonary disease (COPD) |
| Fluid in the lungs | pneumonia |
| condition in which air leaks out of the lungs into the thoracic cavity | pneumothorax |
| symptoms = night sweats, fever, weight loss and blood tinged sputum | tuberculosis |
| Viral illness of the respiratory system | influenza |
| collapsed lung | pneumothorax |
| Alveoli become over dilated and lose their elasticity | emphysema |
| symptoms = runny nose, pressure over the eyes and headache | sinusitis |
| symptoms = fever, muscle pain, fatigue | influenza |
| Chest rises only on 1 side while breathing | pneumothorax |
| Warms, moistens and filters air | Nose |
| Warm and moisten air / give voice resonance | Sinuses |
| Common passageway for food and air | Pharynx |
| Prevents food/drink from entering trachea | Epiglottis |
| Windpipe | Trachea |
| Air passages that branch off trachea to the right and left | Bronchi |
| Small air passages that branch off the bronchi | Bronchioles |
| Hollow sprees of cells where O2 and CO2 exchange | Alveoli |
| Fatty substance that lines the inner surface of alveoli | Surfactant |
| Covers the lungs | Pleura |
| Cavity between the lungs (holds heart, aorta, etc.) | Mediastinum |
| Body cavity that contains the lungs | Thoracic |
| Partition that separates the nose into right and left cavities | Septum |
| Respiratory center of the brain | Medulla Oblongata |
| Ventilation muscle | Diaphragm |
| Gas exchange between the lungs and outside air | External respiration |
| Gas exchange between blood and cells | Internal respiration |
| Bones in the nose | Turbinates |
| temporary stoppage of breathing | apnea |
| difficult, painful or labored breathing | dyspnea |
| normal/easy breathing | eupnea |
| increased depth and rate of breathing | hyperpnea |
| difficulty breathing when lying flat | orthopnea |
| rapid, shallow breathing | tachypnea |
| rapid breathing caused by stress; increase in CO2 level | hyperventilation |
