Subtitle: Do We Breathe Oxygen or Carbon Dioxide?
Breathing is a process that all humans and animals must undergo in order to survive. But what is the substance that we inhale in order to breathe? The answer is oxygen. Oxygen is a colorless, odorless gas that is vital for life. The air we breathe is composed of 78% nitrogen, 21% oxygen, and 1% other gases.
When we inhale oxygen, we then exhale carbon dioxide. Carbon dioxide (CO2) is a colorless, odorless gas that is produced in the body when oxygen is metabolized. Carbon dioxide is a byproduct of cellular respiration, and it is released into the atmosphere when we exhale.
Cellular respiration is the process of breaking down glucose molecules in order to produce energy. During this process, oxygen is used to convert glucose molecules into energy, and carbon dioxide is produced as a byproduct.
It is important to understand that we do not breathe in carbon dioxide. Our bodies are designed to absorb oxygen and exhale carbon dioxide. Oxygen is essential for life, and without it, our cells would not be able to produce energy.
In summary, we breathe in oxygen and exhale carbon dioxide. This process is necessary for us to stay alive and it is essential for our bodies to function properly.
