Respiratory System Notes
Main Idea
1. What human body system
does the respiratory system
work closely with?
Details
The Respiratory System works most closely with the Circulatory
System.
Oxygen is being delivered to the parts of the body.
2. What gas is delivered to
each part of your body?
Carbon Dioxide is being removed from the body.
3. Which gas is removed from
the body?
1. Where does air enter the
respiratory system?
2. What is the purpose of the
mucous in the lining of the
nose?
Air enters through the nose and mouth.
The mucous lining is used to moisten the air and trap particles
and dust.
The hair prevents dust and air-borne organisms from entering
the lungs.
The epiglottis prevents food from going down the trachea.
Nose
Epiglottis
3. What is the purpose of the
hair in the lining of the nose?
4. What is the flap of tissue
called that keeps food and
water from entering the
trachea?
5. Label the nose and
epiglottis on the diagram.
1. Describe the branching of
the trachea into the tiny air
sacs where blood gets rid of
carbon dioxide and picks up
oxygen.

1. What is the largest organ of
the respiratory system?
2. Describe the motions of the
diagram and chest when you
breathe in.
3. Describe the motions of the
diagram and chest when you
breathe out.
1. What gases are exchanged
between the alveoli and the
capillaries in the lungs?
Bronchi
Bronchioles
Alveoli

Respir means ____________Breathe________________.
The lungs are the largest organ of the respiratory system.
The diaphragm and chest expand, creating greater volume thus
lower pressure in the chest cavity causing air to enter the lungs.
The diaphragm and the chest cavity collapse, creating less
volume thus higher pressure in the chest cavity causing air to
exit the lungs.
Oxygen travels from the Alveoli to the Blood and Carbon
Dioxide travels from the blood to the Alveoli.
