Respiratory System

Question 1

What are the immediate effects of exercise on the respiratory system?

Answer 1

Increase in breathing rate, increase in depth of breathing, increase in the removal of carbon dioxide, tidal volume increases.

Question 2

Can you explain the term ‘oxygen debt’?

Answer 2

The amount of extra oxygen required AFTER anaerobic exercise. This DOES NOT happen during aerobic activity.

Question 3

What are the effects of smoking on the respiratory system?

Answer 3

Reduction in oxygen uptake by the red blood cells- they will carry carbon monoxide from the cigarette smoke in preference to oxygen.

Question 4

What are the long term effects of regular training on the respiratory system?

Answer 4

increased number of alveoli, increased strength of the diaphragm, increase lung volume (increased tidal volume and vital capacity).

Question 5

What is the definition of tidal volume?

Answer 5

during normal breathing, the total amount breathed in and out in one cycle.

Question 6

What is the definition of vital capacity?

Answer 6

the maximum you can forcibly breath in and out.

Question 7

Which one of the following is a LONG TERM effect of participation in exercise on the respiratory system?

Answer 7

A. Increase in blood flow
B. Increase in oxygen debt
C. Increase in vital capacity
D. Increase in breathing rate

Question 8

Can you explain what happens during ‘gaseous exchange?

Answer 8

Breathing oxygen into the the alveoli and then breathing out carbon dioxide (by-product).
