Define the term breathing rate
the number of breaths you take in a minute
Define the term tidal volume
the amount of air inspired or expired per breath
Define the term minute ventilation

How do you calculate minute ventilation?
minute ventilation = tidal volume x breathing rate
What is aerobic exercise?
exercising with oxygen
What does the term anaerobic mean?
Without oxygen
When does lactic acid form?

What happens to your intercostal muscles during inspiration?
