Question 2

Definition of tidal volume

Answer 2

Amount of air inhaled or exhaled in a normal breath

Question 3

When our bodies are at rest breathing is slower and shallowing than when exercising this is because the demand for energy is less so

Answer 3

Less air containing oxygen needs to be breathed in and less carbon dioxide needs to be breathed out (as less is produced by the body)

Question 4

Answer 4

increased air flow into and out of your lungs because you need to get more oxygen into your lungs to diffuse into bloodstream for additional energy production and breathe out additional carbon dioxide produced

Question 5

By breathing more deeply when exercising you

Answer 5

inhale more oxygen, exhale more carbon dioxide to allow this to happen tidal volume with increase

Question 6

Definition of vital capacity

Answer 6

Maximum amount of air the lungs can expire after maximum amount they can inspire

Question 7

What is vital capacity made up of

Answer 7

Tidal volume expiratory reserve volume and inspiratory reserve volume

Question 8

what is expiratory reserve volume

Answer 8

maximum volume that can be exhaled

Question 9

what is inspiratory reserve volume

Answer 9
