Flashcards in Topic 1.2.3 Deck (11):
What is the function of the respiratory system?
To get air into the body and carbon dioxide out.
What are the 3 short term effects of exercise on the respiratory system?
Breathing rate increases, increased deoth of breathing and oxygen debt.
What are the benefits of having an increased rate and depth of breathing when exercising?
It increases the removal of carbon dioxide and increases the amount of oxygen taken into the lungs in every breath.
What is the definition of oxygen debt?
The amount of oxygen consumed during recovery above that which would have ordinarily been consumed in the same time at rest.
What are the long term effects of exercise on the respiratory system?
Increased lung capacity, increased vital capacity and increased number of alveoli.
What are the benefits of an increased lung capacity, increased vital capacity and increased number of alveoli when exercising?
Your respirsatory system is stringer, you can take in more air and therefore more oxygen can go to the working muscles.
What is the definition of 'total lung capacity'?
The total volume of air in your lungs after your biggest breath in.
What is the definition of 'tidal volume'?
During normal breathing, the total amount breathed in and out in one cycle.
What is the definition of 'vital capacity'?
The maximum you can forcibly breathe in and out.
What effect does smoking have on the respiratory system?
Smoking will cause a reduction in oxygen uptake by red blood cells as they will carry carbon monoxide from the smoke in preference to oxygen.
