Respiratory System Flashcards
3 ways air is modified
Filters-hair and mucus
Moisten
Warm
What keeps food from going into the lungs or up your nose
Uvula
What is hyperventilation?
Breathing very rapidly. If you breath with a bag, you will be breathing in some CO2
How would you construct a lung model?
2 liter bottle for chest cavity
2 small balloons for lungs
A straw for trachea
Big balloon for bottom of bottle to create the contracting and relaxation of diaphragm
Vital lung capacity(VC)
The max amount of air you have move in and out of your lungs
TV+IRV+ERV
Residual volume(RV)
Air that ALWAYS stays in lungs
About 1 liter
Total lung volume
Total lung capacity(TLC)
VC+RV
Expiratory reserve volume(ERV)
Extra air
Little more than 1 L
Inspiratory reserve volume(IRV)
Larger amounts of air
As much as 3 L
Tidal volume(TV)
Amount of air you take in on a normal breath
.5 L
How do y measure the lung volume of a child
Use the lung volume bag or a subway bag
Why did I have the most difficulty keeping the flow in the middle zone when using the breath control device
It takes a lot of breath control and power
Path of air from nostrils to lungs
Nasal passage-air is modified Pharynx- epiglottis, uvula Trachea-lined with cilia and mucus, ridges of cartilage, larynx Bronchi Bronchioles Alveoli
