What are alveoli surrounded by to allow the exchange of O2 and CO2? -
(answers)Capillaries
What is cilia? - (answers)Tiny hairs in the nose and trachea that wave particles up

elasticity
What is elastic recoil? - (answers)The ability for the alveoli to get filled with air
then return to their normal shape once the air is released

What is reserve amount? - (answers)The amount of extra air you can breathe out
when you force air out of your lungs
What is residual amount? - (answers)The amount of air in your lungs that you
cannot get rid of (even during forced exhaling)
What is vital capacity? - (answers)All the air you can control going in or out of
your lungs (supplemental + reserve = vital)
What is total capacity? - (answers)From the top of your supplemental amount to
the bottom of your residual volume
