| Question | Answer |
|---|---|
| Asthma | A chronic condition where the airways become inflamed and narrow, making breathing difficult. |
| Punctured Lung | Also called a collapsed lung; air leaks into the space between the lung and chest wall causing the lung to collapse. |
| Pulmonary Fibrosis | A disease where lung tissue becomes scarred and stiff, making it harder to breathe. |
| Pulmonary Edema | A condition where fluid builds up in the lungs, making breathing difficult. |
| Hyperventilate | Breathing very quickly or deeply, causing too much carbon dioxide to leave the body. |
| Diffusion | The movement of gases (like oxygen and carbon dioxide) from an area of high concentration to low concentration. |
| Inspiration | The act of breathing air into the lungs (inhaling). |
| Expiration | The act of breathing air out of the lungs (exhaling). |
| Respiratory Rate | The number of breaths a person takes per minute. |
| Pulse Oximetry | A test that measures how much oxygen is in the blood using a small device placed on a finger. |
| Peak Expiratory Flow (PEF) | The fastest speed air can be blown out of the lungs after a deep breath. |
| Peak Expiratory Flow Rate (PEFR) | A measurement of how quickly a person can exhale air; used to monitor asthma. |
| Forced Expiratory Volume (FEV1) | The amount of air a person can forcefully exhale in one second. |
| Bronchodilator | A medication that relaxes airway muscles and opens airways to improve breathing. |
| Upper Respiratory Tract | The part of the respiratory system including the nose, nasal cavity, pharynx, and larynx. |
| Larynx | The voice box; connects the pharynx to the trachea and contains vocal cords. |
| Pharynx | The throat; a passageway for air and food connecting the nose and mouth to the larynx and esophagus. |
| Nasal Cavity | The hollow space inside the nose that warms, moistens, and filters incoming air. |
| Lower Respiratory Tract | The part of the respiratory system including the trachea, bronchi, bronchioles, and lungs. |
| Bronchi | The two main airways branching from the trachea into each lung. |
| Bronchioles | Smaller branches of the bronchi that lead to the alveoli. |
| Alveoli | Tiny air sacs in the lungs where oxygen and carbon dioxide are exchanged. |
| Trachea | The windpipe; a tube that carries air from the larynx to the bronchi. |
| Lungs | The main organs of breathing where oxygen enters the blood and carbon dioxide leaves. |
| Right Superior Lobe (Right Upper) | The top section of the right lung. |
| Right Medial Lobe (Right Middle) | The middle section of the right lung. |
| Right Inferior Lobe (Right Lower) | The bottom section of the right lung. |
| Left Superior Lobe (Left Upper) | The top section of the left lung. |
| Left Inferior Lobe (Left Lower) | The bottom section of the left lung. |
| Horizontal Fissure | The line that separates the right upper and middle lung lobes. |
| Oblique Fissure | The line that separates the lung lobes diagonally in both lungs. |
| Diaphragm | A dome-shaped muscle under the lungs that helps control breathing. |
| Cartilaginous Rings | C-shaped cartilage rings in the trachea that keep the airway open. |
| Epiglottis | A flap that closes over the trachea when swallowing to prevent food from entering the airway. |
| Respiratory Zone | The part of the lungs where gas exchange occurs (respiratory bronchioles and alveoli). |
| Conducting Zone | The part of the respiratory system that moves air to the lungs but does not exchange gases. |
