| Term | Definition |
|---|---|
| Nares | URT- conduction emits air to nasal cavity mucous membranes w hairs prevents passage of debris |
| nasal cavity | URT- conduction nasal septum sep, R&L side inhale & exhale |
| Conchae | URT- conduction superior,middle, inferior lines w PCCE w goblet cells makes air turbulent |
| olfactory epithelium | URT smell |
| paranasal sinus | URT- conduction air filled spaces in skull bones to make lighter moistens and warms skull frontal and sphenoid |
| pharynx | URT- conduction muscular funnel |
| nasopharynx | lined w PSCCE- air only. SUP |
| oropharynx | NK-SSET, air and food. MID |
| laryngopharynx | NK-SSET, air and food. INF |
| Larynx | URT- conduction cartilaginous chamber |
| epiglottis | URT- conduction elastic cartilage covers trachea during swallowing |
| thyroid cartilage | URT- conduction hyaline cartilage holds airway open in sound production |
| cricoid cartilage | URT- conduction hyaline cartilage |
| trachea | LRT- conduction air travels here lines w PSCCE w goblet cells & rings of hyaline cartilage |
| bronchi | LRT- conduction PSCCE hyaline cartilage ensures efficient breathing by bringing air to bronchioles |
| bronchioles | LRT- conduction & resp smooth muscle conduct air to the alveoli for gas exchange & change size |
| alveoli | LRT- Resp simple squamous gas exchange |
| pulmonary arterioles | low oxygen blood blue on models |
| pulmonary venules | high oxygen blood red on models |
| R lung | SUP, MID, INF R horizontal fissure R oblique fissure |
| L Lung | SUP, INF L oblique fissure cardiac notch |
| pleura | serous membrane that surrounds lungs visceral- covers lungs parietal inner wall of thoracic cavity |
| diaphragm | skeletal muscle that helps ventilation |
