5. Bronchi
6. Bronchioles
7. Alveoli
,What are alveoli surrounded by to allow the exchange of O2 and CO2? - 🧠
ANSWER ✔✔Capillaries
What is cilia? - 🧠 ANSWER ✔✔Tiny hairs in the nose and trachea that
wave particles up away and out
What is mucus? - 🧠 ANSWER ✔✔Something that keeps the air warm and

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 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
