Thats only half true. Plants produce food with CO2. Breathing oxygen creates CO2."Carbon dioxide (CO2) is a colorless gas that comprises approximately 0.04% of Earth’s atmosphere. In the human body, carbon dioxide is formed from the metabolism of carbohydrates, fats, and amino acids, in a process known as cellular respiration. While cellular respiration is notable for being a source of ATP, it also generates the waste product, CO2. The body gets rid of excess CO2 by breathing it out. However, CO2 in its normal range from 38 to 42 mm Hg plays various roles in the human body. It regulates the pH of blood, stimulates breathing, and influences the affinity hemoglobin has for oxygen (O2). Fluctuations in CO2 levels are highly regulated and can cause disturbances in the human body if normal levels are not maintained."I was in the EMS pipeline at one time....That CO2 buildup triggers the impulse to breathe is a physiological fact....This is why taking booze away from clinical alcoholics will kill them....Their bodies have become acclimated to the elevated CO2 bloodstream levels from decades of ETOH abuse, to the point that if you take the booze away their lizard brain will think that everything is fine and they don't need to draw their next breath.OK, I'll take your word for that. Which atmospheric gases does the human body need to survive? It would be really helpful if you could please specify the rough amount too. Thank you! | eNotesWrong....Humans need CO2 to trigger the breathing impulse.
Even though that link doesn't support that claim
The thread title has a spelling error, which always triggers my "kick sand" reflex.
I just researched "yawning" as to why it is and what it does. There is no real confirmed explanation. I thought it was due to CO2 buildup in the blood and the body gets a good deep breath to get back to good O2 & CO2 levels. But no.
Then there was a study about brain temperature. No again.
Then there was a monkey study, no results, could be everything or nothing.
Just sayin', CO2 levels in the blood varies somewhat, not sure that variance triggers breathing rates, or breathing depths, or yawns??
Yawn - Wikipedia
Physiology, Carbon Dioxide Retention - StatPearls - NCBI Bookshelf
It does cause yawning and it does trigger breathing...
This is the 2nd sentence from the OP. "CO2 is where humans get their oxygen and plants get their food."
Is this true or wrong?
Add to that the OP title misspelling and my judgment as to the authors stupidity.
CO2 is where humans get their oxygen and plants get their food.
