Respiratory System Physiology

What muscles are used in breathing in and breathing out?

• diaphragm and intercostals
• diaphragm and lungs
• lungs and ribs
• lungs and diaphragm

What is the volume that remains in the lungs even after a forceful exhale

• expiratory reserve
• residual volume
• inspiratory reserve
• total lung capacity

Name the organ label # 6. 

• alveoli 
• bronchi 
• trachea 
• lungs 

Name the structure labeled 8 

• lungs 
• trachea 
• diaphragm 
• alveoli 

A disorder of the lungs called ____ causes the bronchi to become restricted (get smaller) so air can't get to the lungs.

• asthma 
• cold
• influenza 
• bronchitis 

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 

Where in the respiratory tract does the exchange of oxygen and carbon dioxide take place?

• Larynx
• Bronchi
• Trachea
• Alveoli

What is Tidal volume

• The volume of air breathed in and out during one breath

• The maximal amount of air a person can expel

• The amount of blood pumped from the heart

• The additional air that can be forcibly inhaled after normal inspiration

When the diaphragm contracts...

• the volume of the thoracic cavity increases and the pressure decreases, causing air to rush into the lungs.
• the volume of the thoracic cavity decreases and the pressure increases causing air to rush out of the lungs. 

The Maximum Volume of air that you can get in and out of your lungs

• 6000mL
• 4800mL
• 3600mL
• 500mL
