Respiratory System Flashcards
(20 cards)
What are the main roles of the respiratory system?
To supply oxygen from the lungs to the blood and get rid of waste gases like carbon dioxide.
What is the primary waste gas disposed of by the respiratory system?
Carbon dioxide
What is the process of taking air into the lungs called?
INSPIRATION
What is the process of expelling air from the lungs called?
EXPIRATION
How is respiration rate measured?
By counting the number of breaths for one minute by counting how many times the chest rises.
List the components of the respiratory system.
- Nose
- Mouth
- Larynx
- Lung
- Right Bronchus
- Diaphragm
- Pharynx
- Trachea
- Left Bronchus
- Bronchiole
- Alveoli
What does aerobic exercise refer to?
Exercise that requires oxygen for prolonged activity.
Why is the respiratory system important for aerobic exercise?
It supplies the oxygen necessary for energy production.
What is ‘Oxygen debt’?
The amount of oxygen needed to recover after anaerobic activity.
What happens when you perform strenuous activity anaerobically?
Oxygen cannot be supplied quickly enough, leading to an oxygen debt.
What is TIDAL VOLUME?
The amount of air breathed in and out in one normal breath.
What is VITAL CAPACITY?
The maximum volume of air you can breathe out after inhaling as much as possible, usually about 4-5 liters.
What happens to vital capacity with regular exercise?
It increases.
How does regular exercise affect alveoli?
More alveoli become available for gaseous exchange.
What is VO₂ max?
The maximum amount of oxygen your body can use during intense exercise.
Why does a high VO₂ max matter?
It indicates the ability to sustain higher exercise intensities for longer periods without fatigue.
Name a field test used to estimate VO₂ max.
- Cooper 12-Minute Run Test
What is the effect of regular exercise on the number of capillaries?
It increases the number of capillaries, improving the transportation of gases.
True or False: Breath control can help in reducing stress levels.
True
What happens after finishing strenuous activity in terms of breathing?
You need to take big gasping breaths to make up for the oxygen used.
