Since oxygen (O2) and carbon dioxide (CO2) are gases, the process of manner of speaking one in and excreting the other is called gas put back. Oxygen is need for normal transfiguration; lack of it leads to death in a few minutes. Carbon dioxide is a waste product of metamorphosis; if breathing stops, carbon dioxide will quick accumulate to a toxic level in the blood.

Thus our lungs, the organs that turn O2 and CO2 with the atmosphere, are vital since their total failure is quick fatal. We have two lungs, one in the right reference of our chest cage and one in the left(p) (Figure l). environ by them is the heart, a midline organ that tilts slightly to the left inside the chest cage.
