We yawn because We yawn because we need to get rid of CO2, so that would mean if you don't yawn you will eventually die from hypercapnia (too much CO2)!
When you yawn, its because you're a little inactive. When youre not doing anything, you breathe slowly, not letting enough air get to your lungs. So your brain tells you to take a deep breath, which is what we call a 'yawn' -from Taylor (a 12 year old)

Mosquitoes have spiracles, which are tiny tubes carrying air through their bodies. They do not have lungs like we do. They force air in and out through their bodies. They get oxygen like we do but do not breathe in the same manner.
Many people assume that we yawn because our bodies are trying to get rid of extra carbon dioxide and to take in more oxygen. According to this theory, when people are bored or tired, they breathe more slowly. As breathing slows down, less oxygen makes it to the lungs. As carbon dioxide builds up in the blood, a message to the brain results in signals back to the lungs saying, "Take a deep breath," and a yawn is produced.
