When the diapragm relaxes and moves back up, the lungs are...

• expanding with air
• shrinking - pushing air out

The diaphragm contracts and flattens in...

• inhalation

• exhalation

The volume of the lungs decreases during...

• inhalation

• exhalation

When the diaphragm relaxes this creates

• a decrease in chest volume

• an increase in chest volume

• an increase in lung capacity

• no change in air volume

The lower respiratory tract includes

• nasal cavity, buccal cavity, pharynx

• nose, pharynx, larynx, bronchi

• larynx, pharynx, bronchioles, lungs

• trachea, bronchi, bronchioles, alveoli

Given the following structures:

1. larynx

2. nasal cavity

3. pharynx

4. trachea

Which of the following is the correct order that air would flow during inhalation.

• 1,2,3,4

• 2,3,1,4

• 2,1,3,4

• 4,2,3,1

Gases move from a lower pressure to a higher pressure. 

• True
• False

Select ALL statements that are true:

• Increase in volume= increase in pressure

• decrease in volume= increase in pressure

• decrease in volume= decrease in pressure

• Increase in volume= decrease in pressure
