KCC #6 Lungs Restrictive and Obstructive diseases, Gas
Exchange, and Transport Questions with Correct Answers
Obstructive Disease Correct Answer-Loss of elasticity; harder to get gas
OUT due to LOSS of recoil. (Recoil; rebound of the lungs after having
been stretched by inhalation). Loss of alveolar walls and causes gas
trapping.
How does obstructive disease affect volume? Correct Answer--Tidal
Volume stays the same
-Residual Volume increases (a lot)
-Vital Capacity decreases (a little)
-Total Lung Capacity increases
Restrictive Disease Correct Answer-Creation of scar tissue wall and
MORE elasticity due to INCREASE in recoil; harder to get air IN.

Bronchitis Correct Answer-inflammation of the bronchi with partial

Emphysema Correct Answer-A serious disease that destroys lung tissue
and causes breathing difficulties; elasticity loss. Obstructive; hard to get
air OUT.
