What is emphysema? - (ANSWER)Tissues in lungs lose elasticity; tissues can't enough O2 or get
rid of enough CO2
What is lung cancer? - (ANSWER)Cells that do not stop reproducing; can spread to other
locations because lungs are so central and connected to so much; survival is generally less then 5
years from diagnosis
What is elastic recoil? - (ANSWER)The ability for the alveoli to get filled with air then return to
their normal shape once the air is released

What is residual amount? - (ANSWER)The amount of air in your lungs that you cannot get rid of
(even during forced exhaling)
What is vital capacity? - (ANSWER)All the air you can control going in or out of your lungs
(supplemental + reserve = vital)
What is total capacity? - (ANSWER)From the top of your supplemental amount to the bottom of
your residual volume
Main idea - (ANSWER)the most important or central thought of a paragraph or larger section of
text, which tells the reader what the text is about
Topic - (ANSWER)a particular issue or idea that serves as the subject of a paragraph, essay,
