How is carbon dioxide removed from the bloodstream?

CO2 is an interesting gas in regards to the body. CO2 is a constant waste product following production of ATP from glucose. CO2 floats around in the blood stream not as a gas but as bicarbonate. This bicarbonate increases the acidity of the blood. You brain likes to sit at a pH of 7.30-7.45, and when that drops it will force your lungs to breath out CO2 to mantaing that balance. Believe it or not, in a normal functioning human bieng, the goal of breathing is not to take in oxygen (just a lucky happenstance), but actually to get rid of CO2.

i think life is life. many could argue that life is ‘nice’ or ‘fun’ but in the end, it is immaterial and will end. nihilism is my philosophy. nothing matters in the end so why make an effort?

yes. i think it is for sure.
