Slide 15 - Slide

Spirograms:
  • When we breathe air moves into and out of our lungs.
  • We can measure how much air moves at a time and put these measurements into a graph.
  • These graphs are called Spirograms.
  • Take a look at the next slide.

Important words:
You do not need to know all the words in the graph only the most important ones.
  • Vital capacity
  • Residual volume
  • Total lung Capacity
  • Tidal volume

Slide 18 - Slide

Vital Capacity:
  • The maximum amount of air you can move with one large inhalation  followed by a large exhalation.
  • How much is this person's vital capacity?
Vital Capacity
Just under 4 liters.

Slide 19 - Slide

Residual Volume:
  • A small amount of air that always stays behind in the lungs, this is so they do not collapse.
  • How much is this person's Residual Volume?
Residual Volume
Just over 2 liters.

Slide 20 - Slide

Total Lung Capacity:
  • The maximum amount of air a person's lungs can hold.
  • How much is this person's Total Lung Capacity?
Total Lung Capacity
6 liters

Slide 21 - Slide

Tidal Volume:
  • The amount of air a person moves into and out of the lungs when relaxed.
  • How much is this person's Tidal Volume?
Tidal Volume
about 0.8 liters
