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).
A: Humans breathe approximately 432 liters of oxygen per day, and that oxygen helps the tissues in the human body function properly. The body needs approximately 352.8 liters of oxygen per day when the body is at rest. Humans need oxygen to provide nutrients to all of the cells in their bodies.
