The most important aspect to respiration is the effect of pH on the capacity of hemoglobin to retain or release oxygen.
The tricky part of oxygen transport is not capturing the oxygen molecule. That's easy; lots of things combine with oxygen. That's what the iron atom at the center of a hemoglobin molecule does.
The tricky part is getting it to let go when you want it to; i.e., at the cells that need the oxygen. Most of the complex, four-part structure of hemoglobin serves the purpose of facilitating the timely release of the oxygen from the iron.
When carbon dioxide builds up in a tissue because the cells' respiration has produced it after the oxygen was used up, it lowers the local pH because CO2 plus water = carbonic acid. Acid pH changes the shape of the hemoglobin molecule and it lets go of its oxygen easier; just the result you want if the local cells are hypoxic (low on oxygen).
In an oxygen-rich environment, like in the alveoli of the lungs, pH is higher and hemoglobin holds on tighter to the oxygen - again, just what you want to happen at that point.
So, acidity and pH balance effect hemoglobin's oxygen carrying capacity. Some chemicals can poison the respiratory system; a good example is carbon monoxide, which locks the hemoglobin so it cannot release the oxygen at all.
The main function of the respiratory system is the exchange of gases. It brings in oxygen and elmiinates carbon dioxide.
Cartilage in the respiratory system (usually found in the trachea and some small amounts in the bronchi), is to act as a way to keep the passageways open.
The respiratory system has as its primary function the exchange of gases. In animals that means carbon dioxide is released and oxygen is absorbed, in plants they do it the other way around, they inspire carbon dioxide and respire oxygen.
The blood system is only there for the Oxygen to be transported. If you are talking about the job of removeing carbon dioxide from the muscles and replaceing it with oxygen then yes the blood system is very important.
Oh honey, let me set the record straight for you. Teeth are as important to the respiratory system as a bicycle is to a fish. In other words, they have absolutely nothing to do with each other. Teeth are for chewing your food, while the respiratory system is all about breathing in that sweet, sweet oxygen. So, no, teeth are not part of the respiratory system - case closed.
Some important questions to ask about the respiratory system include: How does the respiratory system function to bring oxygen into the body and remove carbon dioxide? What are the main organs involved in the respiratory system and how do they work together? How does smoking or air pollution affect the respiratory system? What are common respiratory disorders and how are they treated?
It is in order to have a proper understanding of how our body works. It is also to teach us how to value these organs which are part of our respiratory system.
