There are a couple of important ways our body uses carbon dioxide:

In respiratory physiology, carbon dioxide is the trigger to breathe. In other words, when you hold your breath, the urgency you feel to take another breath is caused by the buildup of carbon dioxide in your bloodstream. The reason you can suppress the urge to breathe by taking several deep breaths first is that this "washes" much of the CO2 from your system.

Carbon dioxide in the blood is also used to produce bicarbonate. Bicarbonate is an alkaline, and a vital component of the pH buffering system of the body (maintaining acid-base homeostasis). 70%-75% of CO2 in the body is converted into carbonic acid (H2CO3), which can quickly turn into bicarbonate (HCO3−).

Do humans inhale carbon dioxide?

Humans breathe in whatever happens to be in the air when they breathe in. If there is carbon dioxide then they will breathe it in as well as nitrogen and oxygen. However they only use the oxygen for respiration so they breathe out everything else with extra carbon dioxide.


Do Factory's make carbon dioxide?

Only factories that use and burn coal produce carbon dioxide into the atmosphere. Forest fires and humans produce the most carbon dioxide.


Does carbon dioxide provide gas for humans to breathe?

No, Carbon Dioxide is the gas that plants use in Photosynthesis to transform it into oxygen for us to breathe.

What does Humans use to breathe in oxygen and release?

Humans use their respiratory system to breathe in oxygen from the air and release carbon dioxide as waste. This process occurs in the lungs where oxygen from the air is absorbed into the bloodstream and carbon dioxide is removed from the body.


What produes carbon dioxide?

Humans and animals produce carbon dioxide (CO2). They breath in oxygen, and in the mitochondria of cells, it creates carbon dioxide.


Do humans exhale only carbon dioxide?

we also exhale water(h2o) along with carbon dioxide. All the constituents of the air we inhale are in the air we exhale. The proportions differ because of the gas exchange in the lungs.
