Question 1

Inspiration

Answer 1

Breathing in air 20% oxygen + 0.4% carbon dioxide

Question 2

Exhalation

Answer 2

Breathing out : 16% oxygen + 4% carbon dioxide

Question 3

Vital capacity

Answer 3

is the greatest amount of air that can be pass into
and out of the lungs by the most forceful inspiration and expiration.

Question 4

Tidal volume

Answer 4

Is the amount of air inspired and expired with each breath

Question 5

Gaseous exchange

Answer 5

The process of oxygen and carbon dioxide moving between the lungs and blood this exhange occur at the aveoli in the lungs

Question 6

Oxygen debt

Answer 6

The amount of oxygen needed at the end of a physical activity to break down any lactic acid

Question 7

VO2 max

Answer 7

The volume of oxygen an athlete can consume while exercising at maxiumum capacity

Question 8

John is an elite 400m runner. Explain why having a efficient
cardiorespiratory system is important for his sport (3).

Answer 8

An effective cardiorespiratory system in important to John’s performance. For
example, during the race John’s breathing rate (tidal volume) will increase .
John needs to get more oxygen in the blood to the working muscles quickly such as
the Gastrocnemius, Hamstrings and Gluteals .
This is vital for John’s performance as if he doesn’t supply enough oxygen to the
working muscles, he will fatigue faster and not finish the race strongly, which will
lead to getting a slower time.
