lung volume and capacities

**1. Which lung volume represents the amount of air that can be forcibly exhaled after a normal exhalation?**

• Tidal Volume

• Inspiratory Reserve Volume

• Expiratory Reserve Volume

• Residual Volume

2. What is the term for the maximum amount of air a person can exhale after taking the deepest breath possible?**

• Total Lung Capacity

• Vital Capacity

• Functional Residual Capacity

• Inspiratory Capacity

**3. Residual Volume is important because it:**

• Enhances oxygen diffusion

• Prevents the lungs from collapsing

• Increases tidal volume during exercise

• Reduces airway resistance

Which lung capacity includes the Tidal Volume and Inspiratory Reserve Volume?**

• Vital Capacity

• Inspiratory Capacity

• Functional Residual Capacity

• Total Lung Capacity

Functional Residual Capacity (FRC) is the sum of which two volumes?**

• Tidal Volume + Residual Volume

• Expiratory Reserve Volume + Residual Volume

• Inspiratory Reserve Volume + Tidal Volume

• Tidal Volume + Expiratory Reserve Volume
