What it is

The respiration

The breathing process is the mechanism through which vegetables and animal organisms take the energy they need to perform their vital processes and grow. Breathing, which can be regarded as a low-temperature combustion, releases the energy contained in organic compounds that the organism takes in through food, by burning oxygen and releasing carbon dioxide and water. Essentially, whenever we breath in, the oxygen contained in the air reaches our lungs, gets into our blood, is carried to all the cells of our body and there it is used in the combustion processes that produce the energy required to keep us alive. The cells, in their turn, give back to the blood the by-products of combustion: carbon dioxide and water. These substances are carried by the blood to the lungs, which they leave as we breathe out.
