What is chronic bronchitis? - ANSWER-Bronchi swell and become clogged with
mucus
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 heart disease? - ANSWER-Blood vessels are constricted, blood pressure
rises, heart has to work harder, heart wears out more quickly
What is cystic fibrosis? - ANSWER-Genetic (recessive); lungs can get clogged
with mucous
What is mesothelioma? - ANSWER-Lungs become exposed to asbestos and
lose elasticity
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 a spirometer? - ANSWER-an instrument for measuring the air capacity of
the lungs
What is tidal volume? - ANSWER-The amount of air taken in and breathed out in
a typical breath
,What is supplemental volume? - ANSWER-The xtra air that can be inhaled or
exhaled with a deep breath
What is reserve amount? - ANSWER-The amount of extra air you can breathe
out when you force air out of your lungs
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
