• exhale
• inhale
• cough
• hiccup

To take in oxygen

• exhale
• cough
• hiccup
• inhale

Air first enters through the

• lungs
• nose and mouth
• alveoli
• bronchioles

The two main branches from the trachea (one to each lung)

• bronchi
• alveoli
• capillaries
• bronchioles

What is tube that is also known as your wind pipe?

• esophogus
• bronchi
• trachea
• alveoli

What is the dome-shaped muscle that works with your lungs?

• biceps
• triceps
• diaphragm
• rectus abdominus

What is the function of the bronchi?

• Transport air from nose to lungs
• Transport air from trachea to lungs
• Transport air from lungs to alveoli
• Transport air from alveoli to blood

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 

During inhalation, the diaphragm moves upward decreasing the volume of the thoracic cavity.

• True 
• False

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.
