# Lung Volume Capacity Lab

```Amoah
Instructions:
1. Take the mouthpiece of your lung volume lab and either dunk in the alcohol (as described/ shown by Ms.
Amoah) and/or wipe with an alcohol wipe. When cleaned, replace the mouthpiece into the round compartment.
2. Take a deep breath, and blow as much air into the Lung Volume bag as possible. This should be ONE breath!!!
3. When finished, trap the air with your hand closest to the mouthpiece – by wrapping the bag around your hand.
Then use the other hand push the air towards the bottom of your bag – in order to find an accurate volume.
4. Convert your LITERS value to MILLILITERS, and then write your answer under Volume #1.
5. Complete this activity again for your SECOND lung volume.
6. Now take the average of your two volumes to have an average capacity.
7. When finished roll up your bag and return it to the box on your table, for the next class.

3. Answer the following questions:
a. FIRST…look at the chart below and ask yourself this question…”Which Lung Capacity
is represented when I breathe into the Lung Volume Bag?” Then… Circle the capacity
value on the chart you are comparing to your own
b. How do your lung volumes compare to the male/female data?

4. Lung Volume Lab Practice Problems:
Using the data you collected from your lab activity, write
the initials of the type of lung capacity that you found in the lab (hint: it is what your circled in the chart on
the previous page). Put this answer in the box to the left of the Equation section of the chart. Then, fill in
the highest &amp; lowest avg lung capacities in the boxes to the right of the equation section of the chart.
Finally, answer the following questions about the person with the HIGHEST &amp; LOWEST Lung Capacity
in your group. Remember you are calculating YOUR data…not given data. I have given some data to you in the
chart. If you are a boy…use the male given data…and girl…use the girl given data. This is great practice for your
test!!!
***The only GIVEN Information you should USE has already been provided in the chart below***
Write the name of lung
capacity you calculated

Tidal Volume (TV)

Answer the following questions: Make sure you EXPLAIN WHY!!!!
“How do you think the following factors affect Lung Volume Capacity?”
5. Height  (Tall vs. Short)?
6. Age  (Young vs. Old)?
7. Physical Activity  (Non-athletic vs. Athletic)?
8. Smoking (hint: think about emphysema &amp; lung cancer)… how will this affect lung volume capacity?
9. High elevations (in the mountains/ in an airplane)…how will this affect lung volume capacity?
10. Low elevations (bottom of the ocean)…how will this affect lung volume capacity?
