Objective 46 & 47: Relate breathing to cellular respiration & Decide how arterial carbon dioxide concentrations affect ventilation

I was taught about breathing from the age of 7-9 in science class.  I learned what cellular respiration was in BIO 100 from my lovely teacher Mrs. Gess because she brought up the subject on multiple occasion throughout BIO 100 plus there was a whole chapter about it and fermentation.  Cellular respiration would in fact pop up during BIO 210 & 211. Breathing is inhaling of oxygen and exhaling of carbon dioxide through the lungs.  Cellualr respiration is relating to breathing because a cell exchanges two gases with its surroundings during cellular respiration.  The cell takes in oxygen and gets rid of carbon dioxide. The bloodstream keeps cells supplied with oxygen and carries away carbon dioxide.
