Good or bad Carbon Dioxide

Since it is good for my lungs to get carbon dioxide out of my body, why would I drink carbon dioxide, and isn't this bad?

  1. No, this is a superficial comparison. Drinking carbonated beverages does not interfere with breathing.

    1. It'd be really bad if you were a fish.

      1. One would think that if it were bad, people would be keeling over around the world after drinking carbonated beverages.

        1. No, because you are putting it into your stomach, not your lungs. And when you burp it comes right out.

          1. The air you breath in has CO2, the normal amount in the atmosphere. The air breath out is slightly richer in CO2, and a bit less rich in O2, having exchanged those gases with the blood.

            There is also air in your stomach. Some of that you have swallowed. The CO2 from the drink joins that. Excess is released with burping. Very little if any of these gases are absorbed into the blood. The CO2 that you breath out has been generated in the cells. It does not come from your food or drink.

              Also, when the C with the pair of O's do-si-dos and changes partners for quad Hydrogens, the resultant CH4 (methane) finds it's way out the back door.

                from an engineering standpoint, it's quite an impressive feat to ventilate a tank from the bottom.

                  The engineer had a good sense of humor.

                    I try to tell my wife that, but she just wrinkles her nose and leaves the room.
