The proceed of the respiratory system is or else simple in theory: to bring in oxygen from the atmosphere and secure dislodge of cytosine dioxide from the blood. Since o xygen (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 necessary 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 replacement O2 and CO2 with the atmosphere, are vital since their total failure is promptly fatal.
