Answers
Answer:
When we take a breath, we pull air into our lungs that contains mostly nitrogen and oxygen. When we exhale, we breathe out mostly carbon dioxide. Why do we do this?
Our bodies need oxygen to function. After we take a breath, the lungs transfer oxygen to our blood to be transported all over our bodies to help our cells work. Think about it — when you are running, you breathe more heavily to get more oxygen. Oxygen helps our cells work harder by breaking down the nutrients we get from food like sugars. With sugars and oxygen, our cells can create the energy they need to function.
This process also produces carbon dioxide. The carbon dioxide produced is a waste product and needs to be removed. Just like oxygen, carbon dioxide is transferred to blood to be carried to the lungs, where it is removed and we breathe it out. This is important because if we couldn't remove carbon dioxide from our blood, it would take up all the carrying capacity of our blood and we wouldn't be able to get oxygen to the rest of our body. This is another reason you breathe heavier when exercising — you produce carbon dioxide faster and need to get it out of your body to make room for more oxygen.
