The Respiratory System
By Joanna Gong and Austin Yoo
Key Concepts
Key Words
The structure and functions of the lungs
Why do we get hiccups?
Diseases associating the respiration system
How much oxygen our body receives
oxygen
alveoli
carbon dioxide
Gas Exchange
Structures that Air
Passes
1. Nose (nostril) - air enters
body
2. Pharynx - nose to throat
(pharynx)
3. Trachea - the pipe for
throat to lung
4. Bronchus - moves into left
and right bronchi (bronchus)
5. Lung - the air goes from
the lungs to the air sacs
Structure & Functions
moves oxygen from the outside environment
into the body
removes carbon dioxide and water from our
body.
Taking in Oxygen
oxygen ->needed for energy-releasing
chemical reactions taking place in cells
respiration is not breathing.
respiration = chemical reaction in cells
What are hiccups?
diaphragm and nearby muscles convulse ->
briefly gulp in air.
within 35 milliseconds, the glottis slams shut > making one hiccup
Why do we get hiccups?
Usually hiccups are act of the body trying to
protect itself.
ex) hot food, breathing in too much air, eating
too quickly etc)
Asthma
long time lung disease that inflames and
narrows the air ways.
Asthma
airways swell, muscles
tighten, and mucus,
make it hard to
breathe.
Bronchitis
-acute inflammation
of the air passages
within lungs
-trachea and bronchi
= infected
Small Activity
The differences in your body when you inhale
and exhale
feel your ribs while you breathe
how does it change?
what do you think is happening with the lungs?
Inhaled Air
Inhaled Air
Exhaled Air
Exhaled Air
Differences
- oxygen decrease (5%)
- Carbon Dioxide increases
- Other gases increase

What is the respiratory system?
Name one part of the system and explain it
Explain about one disease
