Which of the following lung capacities is the volume of air that can be maximally exhaled after a maximum inhalation?

• inspiratory capacity
• functional residual capacity
• vital capacity
• total lung capacity

Given the following structures:
1. larynx
2. nasal cavity
3. pharynx

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

• 1,2,3,4
• 2,3,1,4

• 4,2,3,1 

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.
