Cellular respiration is the process in which the chemical bonds of energy-rich molecules such as glucose are converted into energy usable for life processes. Oxidation of organic material—in a bonfire, for example—is an exothermic reaction that releases a large amount of energy rather quickly. The equation for the oxidation of glucose is:
C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy released (2830 kJ mol−1)
In a fire there is a massive uncontrolled release of energy as light and heat. Cellular respiration is the same process but it occurs in gradual steps that result in the conversion of the energy stored in glucose to usable chemical energy in the form of ATP. ATP is known as the universal currency because when the phosphoanhydride bonds in ATP are hydrolyzed in an exergonic reaction, the energy yield is 30kJ per mole under standard conditions. Waste products (CO2 + H2O) are released through exhaled air, sweat and urine

When the individual cells take in oxygen and expel CO2.
(BTW - how is this an Anthropology questions?!?)
