Everybody breathes without thinking, in fact according to howstuffworks.com, you breathe 15 to 25 times a minute. Breathing is a part of our Autonomic System. That means we dont have to remember, try or even think about breathing, this system does that for us. Inside your chest, there is a cavity filled with two bag-like organs called the lungs, which are protected by the rib cage. They are made of spongy tissue, which is a type of tissue that resembles elastic. It can stretch, and constrict as we breathe in and out.
When you inhale, whether it be from your nose or mouth, oxygen filled air flows through your throat area, down an airway called the trachea, and fills your lungs.
From there, the oxygen attaches to hemoglobin in red blood cells, which are specifically designed to carry oxygen to cells that are in need of it.
Once the oxygen is attached to the RBC (red blood cells), it pushes the carbon dioxide away(which have binded to the RBC's from the many chemical reactions that happen in our body). As soon as the oxygen knocks them off of the RBC they were once attached to, they then travel back to the lungs. At this point, you will exhale all the unwanted CO2, only to repeat the process and repeatedly get rid of carbon dioxide.
Therefore, the lungs work to keep as much carbon dioxide out of your body as they can at a time by replacing it with oxygen.
