Every cell in your body inhales the oxygen and exhales the carbon dioxide – a process called respiration. Breathing is important because our cells constantly need a new supply of oxygen so they can produce energy – without this vital oxygen, cellular function is impaired, and damage or cell death is possible.

Importance Of Breathing. Breathing is important for two reasons. It is the only means to supply our bodies and its various organs with the supply of oxygen which is vital for our survival. The second function of breathing is that it is one means to get rid of waste products and toxins from the body.

The danger is that if deep breathing is done incorrectly one can invite lowered carbon dioxide levels, arrested personal improvement, restrictive lung disease, lack of oxygen, increase in difficulty breathing and shortened lifespan. … Breathing deeper often upsets the chemical axis of breathing.

(We breathe because oxygen is needed to burn the fuel [sugars and fatty acids] in our cells to produce energy.) (Oxygen is brought into the lungs via breathing, where it is transported by red blood cells to the entire body to be used to produce energy.

One critical role that oxygen plays in the body is that it is used to oxidize our food, in the process of cellular respiration, thus releasing energy, which is eventually stored in ATP in the electron transport chain in mitochondria, and in glycolysis in the cytoplasm.
