This week, we are going to talk about our idea of an industrial application using our Jr.Roger for inspiration. As we said earlier, we know that frogs are able to:
1. Breath through their skin.
2. Absorb water through their skin.
With these 2 abilities of their skin, we know that H2O, CO2 and O2 are able to pass through the frog skin. To make sure the carbon dioxide and oxygen are able to pass through the skin, it should be kept moist.
There are blood vessels near the surface of the skin and when the frog is underwater, oxygen will diffuses into the blood directly. But when the frog is not submerged in the water, it will breathes by a process called buccal pumping. This process is the breathing process similar to human, but the chest muscles are not involved in the respiration. Besides that, the frogs have no rids or diaphragm to help move air in and out.
Thus, the frogs will puff out their throat and draw air in through the nostrils, which in many species can ten be closed by valves. When the floor of the mouth is compressed, air is forced into the lungs.
Within this week, we have decided to propose an idea of a AIR PURIFIER
In the diagram above, it shows that the first layer of the frog skin is
stratified epithelium.
As we know, the functions of epithelium are:
1. secretion
2. propulsion of mucus by ciliary action
As we know, this is located at the trachea of our lungs. But, it also located at the first layer of the frog skin.
It is located at the frog skin is because it consists of alveoli. This part is where the gas exchange take place.
Besides gas exchange, it is also a protective layer to the air-born pathogens and toxic gases. Thus, we can have a air purifier for every processes that will release toxic gas.
Stay tuned for the next post regarding the components of the air purifier! :D
