The primary importance of oxygen is that it is critical for cellular respiration in all aerobic organisms oxygen also has medical uses including oxygen therapy, high-pressure treatment, and in protective suits made for space and deep sea exploration oxygen destroys harmful bacteria in human bodies . History of oxygen oxygen was officially discovered in 1774, but had been discovered by several chemists without realizing it was a distinct element joseph priestly is usually given credit for the discovery of oxygen, however it has been said that carl wilhelm scheele had also independently discovered the element.

Cfcs are compounds that react with ozone in the presence of uv light by splitting the three oxygen atoms into one o 2 molecule and one clo molecule the clo molecule may react with a single oxygen . The ultimate discovery of the two principal constituents of air, nitrogen and oxygen, a discovery of epochal importance in science, was made only in the late 18th century. The history of oxygen from discovery to clinical application for patients with chronic lung disease represents a long and storied journey within a relatively short period, early investigators not only discovered oxygen but also recognized its importance to life and its role in respiration.

Lavoisier’s theory that combustion was a reaction between the burning substance and the gas oxygen, present only to a limited extent in the atmosphere, was based on scientific principles, the most important of which was the law of the conservation of matter (after einstein’s relativity theory, of matter and energy): the total amount of . The history of portable oxygen while the techniques used have no resemblance to how oxygen therapy is done today, the importance of it was known back in the 1600s . The discovery of oxygen has been described as “the most important discovery in the history of science” science historians have identified at least three key individuals (lavoisier, scheele, priestley) to be credited with oxygen’s discovery in the late 18 th century.
