We breathe in oxygen and some of this carbon dioxide. When we exhale, we breathe out less oxygen but more carbon dioxide than we inhale. Paul Roberts, Lake Cathie. The carbon we breathe out as carbon dioxide comes from the carbon in the food we eat. The carbohydrates, fat and proteins we consume and digest are eventually converted by a number of different biochemical pathways in the body to glucose (C6H12O6).

Oxygen is needed to generate energy in cells and carbon dioxide is a waste product that can acidify the blood if not expelled.he lungs are the most important organ in your body. Without our lungs, we wouldn't be alive. Our lungs helps us inhale oxygen and exhale carbon dioxide. The lungs are also th â¦ e biggest organ in our body. So the lungs are important.
