The Respiratory System: Vocabulary Part I
1) inhale: to breathe air into your body through your mouth
or nose.
2) lungs: organs that fill with air when you inhale and
empty of air when you exhale.
3) exhale: to breathe out.
4) diaphragm: is the muscle located below your lungs
that contracts and expands to control your breathing.

The Respiratory System: Vocabulary Part II
5) bronchi: are the branches of tubes that get smaller
and smaller
6) capillary: is a tiny blood vessel.
7) alveoli: are very thin air sacs at the end of the bronchi
tubes that aids in the exchange of oxygen and carbon
dioxide.
8) diffusion: is the movement of particles from areas of
high concentration to low.

The Respiratory System: Main Ideas
1) What does the respiratory system do? (pg.
134-135)
a) It transports the air you breathe and exchanges oxygen
and carbon dioxide between your blood and your
tissues.
 Quick Check (pg. 135)
-Critical Thinking: Explain how the
diaphragm and lungs work together?
a) The diaphragm helps the lungs contract and expand
which allowing the lungs to take in and push out air.

2) Where does gas exchange take
place? (pg. 136-137)
a) The alveoli.
 Quick Check (pg. 137)
-Critical Thinking: Carbon dioxide is a human
waste. Is this true for plant, too?
a) No. Oxygen is a plant waste.
