| Question | Answer |
|---|---|
| Asthma | A condition where the airways become inflamed and narrow, making it hard to breathe. |
| Punctured Lung | A condition where air leaks into the chest cavity and causes the lung to collapse. |
| Pulmonary Fibrosis | A disease where lung tissue becomes scarred and stiff, making breathing difficult. |
| Pulmonary Edema | A condition where fluid builds up in the lungs and makes it hard to breathe. |
| Hyperventilate | Breathing very fast and deeply, which causes too much carbon dioxide to leave the body. |
| Diffusion | The movement of molecules from an area of high concentration to an area of low concentration. |
| Inspiration | The process of breathing air into the lungs. |
| Expiration | The process of breathing air out of the lungs. |
| Respiratory Rate | The number of breaths a person takes per minute. |
| Pulse Oximetry | A test that measures how much oxygen is in the blood. |
| Peak Expiratory Flow (PEF) | The fastest speed at which a person can blow air out of their lungs. |
| Peak Expiratory Flow Rate (PEFR) | A measurement of how quickly air can be forced out of the lungs. |
| Forced Expiratory Volume (FEV1) | The amount of air a person can forcefully exhale in one second. |
| Bronchodilator | A medication that relaxes and opens the airways to help people breathe easier. |
| Upper Respiratory Tract | The part of the respiratory system that includes the nose, nasal cavity, pharynx, and larynx. |
| Larynx | The voice box that allows sound to be produced and protects the airway. |
| Pharynx | The throat that connects the nose and mouth to the trachea. |
| Nasal cavity | The space inside the nose that warms, moistens, and filters air. |
| Lower Respiratory Tract | The part of the respiratory system that includes the trachea, bronchi, bronchioles, lungs, and alveoli. |
| Bronchi | Two large tubes that carry air from the trachea into the lungs. |
| 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 that carries air from the larynx to the bronchi. |
| Lungs | Organs that allow the body to take in oxygen and remove carbon dioxide. |
| 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 upper section of the left lung. |
| Left Inferior Lobe (Left Lower) | The lower section of the left lung. |
| Horizontal Fissure | The line that separates the upper and middle lobes of the right lung. |
| Oblique Fissure | The line that separates the lobes of the lungs diagonally. |
| Diaphragm | A large muscle below the lungs that helps control breathing. |
| Cartilaginous rings | Rings of cartilage in the trachea that keep the airway open. |
| Epiglottis | A flap of tissue that covers the trachea when swallowing so food does not enter the airway. |
| Respiratory zone | The part of the lungs where gas exchange happens in the alveoli. |
| Conducting zone | The part of the respiratory system that moves air to the lungs but does not exchange gases. |
