Functions of Paranasal Sinuses (3):

1. Lighten the Skull

-Mucosa
-Submucosa
-Hyaline Cartilage
-Adventitia

9

There are approximately _______ rings of Hyaline Cartilage in the trachea.

16-20

10

What is the Carina and what is unique about it?

1. Carina: The ridge of separation around T-5 vertebrae where the trachea becomes the bronchi.
2. It is the most sensitive area to triggering the cough reflex.

Function of the pleural sac:

Reduce Friction (Increase surface tension)

12

The Cardiac Notch is seen on the ______.

Left Lung

Describe the 2 types of alveolar cells and their functions:

1. Type 1 Cells: (squamous) Main site of gas exchange, form continuous lining of epithelium.
2. Type 2 Cells: (cuboidal) Septal cells that contain microvilli that secrete Surfactant to reduce surface tension and lower the tendency of alveoli to collapse.
