4. Crash Course Biology- The Respiratory System

5. **MEASURE EVERYTHING IN CENTIMETERS**
Lung Capacity Lab
You will be completing a lab to address two different types of lung volumes
Tidal Volume: amount of air in a normal breath
Vital Capacity: Amount of air that can be forced out
Why?
**MEASURE EVERYTHING IN CENTIMETERS**

6. Lab Discussion
What was the difference between tidal volume and vital capacity?
What was the effect of jogging on these 2 volumes?
Why is it important to know tidal volume and vital capacity?

7. Average for Humans Average Tidal Volume: .5L (500 cubic centimeters)
Average Vital Capacity: 4-6L ( cubic centimeters)

9. Exit Quiz What is tidal volume? What is vital capacity?
How does exercise effect vital capacity short-term? Long-term?
What is the end goal of our body’s respiratory system?
