Respiratory System Quiz

What is the typical resting tidal volume for trained individuals?

• 500-700 milliliters

• 100-200 milliliters

• 800-1000 milliliters

• 200-300 milliliters

How does tidal volume change during moderate exercise?

• Decreases

• Stays the same

• Fluctuates

• Increases

What is the typical resting tidal volume for untrained individuals?

• 250 mL

• 750 mL

• 500 mL

• 1000 mL

Describe the changes in tidal volume during recovery after exercise. 

• TV remains higher than resting levels during recovery Because oxygen is needed for recovery process or need to repay O2 debt 

• Tidal volume/TV drops (as soon as exercise ends) 

• Rapid decrease at first Followed by a more gradual decrease 

• All of the them

Explain the changes in minute ventilation during exercise of different intensity.

• Minute ventilation is not affected by exercise intensity.

• Minute ventilation decreases with higher intensity exercise.

• Minute ventilation increases with higher intensity exercise.

• Minute ventilation remains the same regardless of exercise intensity.

Calculate the minute ventilation using the given data for a specific exercise intensity.

• Minute ventilation = Heart rate x Blood pressure

• Minute ventilation = Oxygen consumption / Carbon dioxide production

• Minute ventilation = Lung capacity x Exercise duration

• Minute ventilation = Tidal volume x Respiratory rate

Compare the resting tidal volumes between trained and untrained individuals.

• Resting tidal volumes are not affected by training.

• Untrained individuals have higher resting tidal volumes.

• Resting tidal volumes are the same for trained and untrained individuals.

• Trained individuals have higher resting tidal volumes.

What factors can affect the resting tidal volume of an individual?

• Shoe size, blood type, zodiac sign

• Height, weight, hair color

• Age, gender, physical fitness, and lung diseases

• Favorite color, favorite food, favorite movie

Explain the relationship between breathing frequency and minute ventilation.

• Minute ventilation is only determined by tidal volume

• Minute ventilation decreases as breathing frequency increases

• Breathing frequency has no impact on minute ventilation

• The relationship between breathing frequency and minute ventilation is that minute ventilation is the product of breathing frequency and tidal volume.

How does minute ventilation change with an increase in exercise intensity?

• Minute ventilation increases

• Minute ventilation decreases

• Minute ventilation remains the same

• Minute ventilation has no effect on exercise intensity
