The structure indicated here (with the wooden pointer) is comprised of what tissue?
Elastic Cartilage
B is comprised of what type of epithelial cells?
Pseudostratified ciliated columnar epithelium
What do the cilia in the trachea DO?
Move mucus posteriorly
Look BELOW B. What is that layer of the trachea called?
Adventitia
Blood CARRIES gases to and from tissues (there's a reason this is $500- it's not what you first think)
Gas transport
What is the function of pleural fluid?
lubricates the pleura, allows sliding
What does this illustration represent?
Boyle's Law
Structure B type II cells produce a substance. What is the substance AND what does it do?
Surfactant reduces surface tension in the alveolar walls
Why does there appear to be two layers of hyaline cartilage on this slide?
The specimen was cut at an angle.
What do you call the amount of air inhaled or exhaled with each breath under resting conditions?
Tidal Volume
