Respitory
| Term | Definition |
|---|---|
| Asthma | A condition where the airways become inflamed and narrow, making it hard to breathe. |
| Punctured Lung | When 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 breathing difficult. |
| Pulmonary Edema | A buildup of fluid in the lungs that makes it hard to breathe. |
| Hyperventilate | Breathing very fast or deeply, often causing too much carbon dioxide to leave the body. |
| Diffusion | The movement of gases (oxygen and carbon dioxide) from an area of higher concentration to lower concentration. |
| Inspiration | Breathing air into the lungs (inhaling). |
| Expiration | 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 sensor on the finger. |
| 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 medicine that relaxes airway muscles and widens the airways to help breathing. |
| Upper Respiratory Tract | The part of the respiratory system that filters, warms, and moistens air before it reaches the lungs. |
| Nasal Cavity | The hollow space inside the nose where air enters and is filtered. |
| Pharynx | The throat; a passageway for air and food. |
| Larynx | The voice box that contains the vocal cords and helps keep airways open. |
| Lower Respiratory Tract | The part of the respiratory system that carries air to and from the lungs. |
| Trachea | The windpipe that carries air from the larynx to the bronchi. |
| Bronchi | Two large tubes that branch from the trachea into each lung. |
| Bronchioles | Smaller branches of the bronchi inside the lungs. |
| Alveoli | Tiny air sacs where oxygen and carbon dioxide are exchanged. |
| Lungs | The main organs of breathing that allow gas exchange. |
| Right Superior Lobe (Right Upper) | largest of the three lobes, vital for oxygenating blood |
| Right Medial Lobe (Right Middle) | ventilated and perfused like other lung segments, with oxygenated blood supplied by branches of the right bronchial artery |
| Right Inferior Lobe (Right Lower) | contributing about 30% of total lung volume |
| Left Superior Lobe (Left Upper) | located above the oblique fissure |
| Left Inferior Lobe (Left Lower) | base of the left lung, resting on the diaphragm, essential for respiration |
| Horizontal Fissure | The line that separates the right upper and right middle lobes. |
| Oblique Fissure | The line that separates the upper and lower lobes of the lungs. |
| Diaphragm | A dome-shaped muscle under the lungs that helps with breathing. |
| Cartilaginous Rings | C-shaped rings in the trachea that keep the airway open. |
| Epiglottis | A flap of tissue that closes over the trachea when swallowing to keep food out. |
| Conducting Zone | The parts of the respiratory system that move air but do not exchange gases (nose → bronchioles). |
| Respiratory Zone | The parts where gas exchange happens (respiratory bronchioles and alveoli). |
