Document Summary

Inferior to vocal folds pseudostraiied ciliated columnar epithelium (epithelial lining of upper vs lower porion of larynx. Cilia moving downwards on top half, cilia moves upwards on lower tract, moving against gravity) Vocal folds as sphincter to guard airway. Valsalva"s maneuver (nose & mouth: medical examine. Air passing through pharynx through trachea has to go through the larynx. Most violent coughing is iniiated when foreign objects contact the carina of the trachea. Press ist into the abdomen with quick upward thrusts, moion similar to j in and then up. Repeat the thrusts unil the object is dislodged & expelled. * spar of carilage on last, expanded tracheal carilage. * point where trachea branches into two main bronchi. Carilage rungs are c shaped rather than coninuous. Ater drinking, someimes the throat needs room to expand. Avoid drugs which inhibit coughing (last line of defense). Air passages branch 23 orders (secondary, teriary) bronchial tree bronchioles (warm, moisten & clean)
