These are the noble gases; but they aren't completely unreactive !
-It's hard to find -It's Expensive to create energy plants to send the natural gases
When inert gases are combined with, or create bonds with, other elements, they make explosives. Otherwise, naturally, theyâ??re very unreactive.
oxygen and carbon dioxide ('O' and 'CO2') . We breath in oxygen and breath out carbon dioxide (the unwanted gas). Oxygen is used is transported through the blood stream (haemoglobin) tis the main gas in circulation.
Nature creates greenhouse gasses by having cows fart.
The pulmonary circulation works closely with the respiratory system at the alveoli. There, capillaries are in close proximity to the air sacs, and gases are exchanged at this point.

Respiration need transportation of respiratory gases. This is done by circulation system

Argon is one of the Noble Gases, so it is inert, meaning it has a full outer shell and therefore never combines with any other element. The noble gases are also called the inert gases. The six noble gases are helium, neon, argon, krypton, xenon, and radon. They are members of group 18 of the periodic table (right side). They are odorless, colorless gases

To exchange gases such as co2 and o2
Hydrogen and Helium are the two main gases present in the stars Hydrogen combines with other hydrogen atoms during proton proton cycle
The variation of pressure in liquids and gases in everyday phenomena is referred to in Pascal's Principal and produced by gravity and the Earth's rotation.
Magnetic Fields
Almost any element, including most of the noble gases, can form covalent bonds, but non-metallic elements other than the noble gases form the most.
