Vallecula Depression at the back of the tongue. It is an anatomical landmark for intubation.
Glottis Space between the vocal cords. This is the narrowest point where air goes through in adults.
Epiglottis Flap of skin that protects the trachea from aspiration.
Carina Bottom of trachea where the mainstems split into left and right. The tip of the ET tube should be 2" above to avoid irritation.
Divisions of the Pharynx Nasopharynx (Nose straight back,contains adenoids and eustachian tubes), Oropharynx (Mouth straight back, contains tonsils and vallecula), Laryngopharynx (Bottom of throat, contains voicebox, epiglottis, esophagus)
Main functions of the nose Filter, Humidify, and Warm inspired air
Differentiate the Right Bronchi from the Left Bronchi... Right Bronchi is Wider, Shorter by 5cm, and more vertical with a 25 degree angle. Left Bronchi is narrower, Longer by 5 cm, and more horizontal with a 40-60 degree angle
Turbinates Are located in the nose, there are 3 layers (superior, middle, and inferior) they play a major role in humidification and warming of inspired air.
Cell types in the Alveoli Type 1 ( thin/broad, 95% of cells, Diffusion of gases) Type 2 (cuboidal, 5% of cells, Make and Store pulmonary surfactant) Type 3 (Alveolar macrophages, protect and serve the alveolus)
How many Lobes and Segmental Bronchi do the Right and Left lung contain? Right Lung (3 Lobes, 10 Segmental Bronchi) Left Lung (2 Lobes, 8 Segmental Bronchi)
The adult Trachea is how long and how wide? 11-13 cm Long and 1.5-2.5 cm Wide
Where is Pseudostratified ciliated columnar epithelium found? In the tracheobronchial tree starting with the trachea going down to the respiratory bronchioles (excludes the Alveolar ducts and sacs)
Parts of the tracheobronchial tree Trachea, Right and Left Mainstem, Lobar Bronchi, Sengmental Bronchi, Subsegmental Bronchi, Bronchioles, Terminal Bronchioles, Respiratory Bronchioles, Alveolar Ducts, Alveolar Sacs.
Parts in the conducting zone of the tracheobronchial tree Trachea,Right and Left Mainstems, Lobar Bronchi, Segmental Bronchi, Subsegmental Bronchi, Bronchioles, Terminal Bronchioles.
Parts in the Respiratory Zone of the tracheobronchial tree Respiratory Bronchioles, Alveolar Ducts, Alveolar Sacs
Cartilagenous Airways (In conducting zone) Hold open airways- trachea, Right and Left Mainstems, Lobar Bronchi, Segmental Bronchi, Subsegmental Bronchi.
Noncartilagenous Airways (In conducting zone) Bronchioles, Terminal Bronchioles.
Parts in Respiratory Zone responsible for gas exchange) Respiratory Bronchioles, Alveolar Ducts, Alveolar Sacs.
Functions of the upper airway act as a conductor of air, humidify and warm the inspired air, Prevent foreign materials from entering tracheobronchial tree, Serve as an important area involved in speech and smell.
Pulmonry Lymphatics (Function, Location, and Density) Function- remove excess fluid that leaks out of pulmonary capillaries.
