Respiratory System Flashcards
What does the respiratory system do?
- gets oxygen to the blood
- removes waste products (eg CO2)
How do you measure the efficiency of the Respiratory system
- Tidal Volume
- Vital capacity
What is Tidal Volume
The amount of air breathed in and out with each normal breath
What is Vital Capacity
The maximum amount of air that can be made to pass in and out of the lungs
What are the long term effects of the respiratory system
- improved efficiency
- increase lung volume
What does it mean by improved efficiency
- more alveoli
- more oxygen absorbed
- more capillaries
What does it mean by increased lung volume
A larger vital capacity
Define Oxygen Debt
The extra oxygen consumed during recovery from a period of strenuous physician activity, compared with the usual amount consumed over the same length of time at rest
What are the immediate effects of exercise in the Respiratory system
- increased breathing rate
- increased depth of breathing
Why is breathing rate increased
To ensure enough oxygen is getting in the blood
Why is the depth of breathing increased
To get more oxygen in the body
What effect does smoking have on the respiratory system
It makes the lungs less stretchy and efficient
