Respiratory System
| Term | Definition |
|---|---|
| Upper respiratory system | Nares, Nasal cavity, hard palate, soft palate, uvula, oral cavity, pharynx, esophogus, larynx, thyroid gland, hyoid bone |
| Parts of the larynx | epiglottis, vocal folds, glottis, thyroid cartilage, cricoid cartilage, arytenoid cartilage |
| Lower respiratory system | Trachea, respiratory tree, alveoli, lungs, diaphragm |
| Parts of the trachea | ciliated, pseudostratified epithelium, goblet cells, catilaginous rings |
| Parts of the respiratory tree | Bronchi, Terminal bronchioles, Bronchioles, respiratory bronchioles |
| Parts of the alveoli | alveolar ducts, alveolar sacs, respiratory membrane |
| Parts of the lungs | lobes, pleura, pleural cavity |
| Microscope slide of trachea | CSE, goblet cells, lamina propria, mucosa, submocosa, hyaline cartilage, adventitia |
| Microscope slide of lung tissue | alveolar duct, sac and alveoli |
| tidal volume | Tidal volume is the amount of air inhaled or exhaled during a normal breath. It typically ranges from 500ml to 700ml in adults. Factors such as age, sex, body size, and physical activity level can affect tidal volume. |
| vital capacity | Vital capacity is the maximum amount of air a person can exhale after a maximal inhalation. It is an important measurement in pulmonary function tests and can be affected by various respiratory conditions, such as asthma, COPD, and pulmonary fibrosis. |
| inspiratory capacity | Inspiratory capacity (IC) is the maximum volume of air that can be inhaled after a normal exhalation. It is the sum of tidal volume (TV) and inspiratory reserve volume (IRV). IC = TV + IRV |
| inspiratory reserve volume | The inspiratory reserve volume (IRV) is the maximum amount of additional air that can be inhaled after a normal, quiet breath. It represents the lung's capacity to take in extra air beyond a regular inhalation. |
