Vital Capacity!

1. How does your vital capacity compare to others in the class? Describe some reasons why you think your vital capacity is what it is. Why are the highest and lowest vital capacities the way they are?


My vital capacity is in fact quite low compared to the rest of the classes. My vital capacity was only 2500 while most would have above that. I have played the tenor saxophone for five years so I thought I would have a higher capacity , but I also have asthma so it would make sense that I would have a lower capacity than most. The highest and lowest vital capacities are the way they are because showcases actual lung strength and the higher it is on the scale the more healthy your lungs are.

 2. How much air is in a usual breath? Why are our breaths the volume that they are?

The typical or average amount of air is 5oo ml. For girls it tends to be two liters while boys are four.
The breaths volume are the way that they are because it depends on the athletic endurance, body sizes and frames.

3. How is the mechanism of exhaling forcefully different than a usual exhalation? Why would practice at this via exercise/instrument playing/singing make you better at it?

When we exhale forcefully, we are voluntarily exhaling air while usual exhalation is involuntarily exhalation. This practices will make it easier to breathe and/or create healthier lungs because it conditions the lungs for a higher vital capacity.
