Take one of the balloons and cut off the bottom part leaving you with only the top part that may resemble a very small swim cap.
Rubber sheeting lung functio.
For example during a lifetime a coal miner may inhale 1 000 g of dust into his lungs.
Trachea when rubber sheet is pulled down volume of bell jar increases decreasing pressure inside balloons and drawing air in.
For this reason epdm material is an excellent medium for outdoor uses.
Mgc diagnostics products are unparalleled in quality accuracy and ease of use.
H weight 1 5 lb.
When the diaphragm rubber sheet moves down the volume inside the glass jar thorax increases.
Diaphragm glass tube into balloons.
As the rubber sheeting is pulled down the lungs inflate.
When using the lung function model what part of the respiratory system is represented by.
Luckily the lungs have another function they have defense mechanisms that protects them by removing dust particles from the respiratory system.
The lung model shows inhalation.
Integrate the latest advances that today s technology affords ensure accuracy through superior design and then back up each and every product with consistently stellar support.
Our simple approach has endured.
It achieves an ideal balance to create an all purpose weather resistant rubber.
This increase in volume causes a decrease in pressure.
The hole doesn t need to be too large about 2 3 mm.
Strong rubber sheet is used to perform the function of the diaphragm as the diaphragm is pulled down the atmospheric pressure is lowered in the plastic chamber which inflates the lungs balloons when diaphragm is released the lungs deflate approximate size 8 dia.
As the rubber sheeting returns to its original position the lungs deflate.
Rubber sheet at the bottom.
Epdm sheet rubber is a versatile blended sheet epdm sheet rubber is a versatile blended sheet composed of ethylene propylene diene monomer and styrene butadiene rubber.
Using the thumbtack or nail poke a hole in the bottom.
