|
Pharyngeal Tonsil |
Also known as the Adenoids are located in the Nasopharynx region. |
|
|
Eustachian Tubes |
Also know as the Pharyngotympanic (auditory) Tubes are located in the Nasopharynx region. |
|
|
What are the vocal cords doing during a quiet inspiration? |
They move apart and widen the glottis. |
|
|
What do the vocal folds do during exhalation? |
They move slightly toward the midline but always maintain an open glottal airway. |
|
|
Structures of the Tracheobronchial tree. |
Trachea, Right and Left Main stem bronchus, Carina, branches to upper lobe, branches to middle lobe, branches to lower lobe. |
|
|
Canals of Lambert |
Appear between the inner lumina surface of the terminal bronchioles and the adjacent alveoli. |
|
|
Pores of Kohn |
Small holes in the walls of the interalveolar septa. They prevent gas flow. |
|
|
Mediastinum location |
Is a cavity in the center of the thoracic cage between the right and left lungs. |
|
|
Mediastinum contents |
The trachea, heart, the major blood vessels that enter and exit the heart, various nerves, portions of the esophagus, the thymus glad, and the lymph nodes. |
|
|
Sternum structures |
Manubrium sterni, the body of the sternum, and the xiphoid process. |
|
|
Manubriosternal |
Also know as the sternal angle or angle of Louis. It is the joint between the manubrium and the body of the sternum. |

|
|
Upper airway structures |
Nose, oral cavity, pharynx, and the larynx |
|
|
Right and left main stem bronchus angles off the trachea |
Right branches off at about a 25 degree angle. Left firms am angle of 40 to 60 degrees. |
|
|
Which main stem bronchus is bigger |
The right is wider, more vertical, and about 5 cm shorter than the left. |
|
|
Tracheobronchial trees Bifurcation |
Trachea branches to the left and right main stem bronchi, then they each divide into the upper middle and lower Lobar bronchi. The third generation of bronchi branch of the Lobar bronchi to firm the Segmental bronchi. The Tracheobronchial tree continues to subdivide between the fourth and approximately the ninth generation into progressively smaller airways called subsegmental bronchi. |
|
|
Accessory muscles of inspiration |
External intercostal, scalenus muscels, sternocleidomastiod muscels, pectoralis major, and the trapezius muscles. |

|
|
Normal PaO2 levels |
Partial pressure of oxygen in the alveoli. 80 to 100 |
