Oxygen - Gift Of Life

This is an article about oxygen - one of the basic elements of life.

The five basic elements of life are: oxygen, hydrogen, carbon, nitrogen and sulphur. All these elements have their own role in all biological processes. Of these five basic elements of life, oxygen has one exceptional property:

Oxygen atoms can easily bound to other molecules. This is why there is oxygen practically everywhere:

there is hardly no materia on earth which would not be of oxygen.

There is nothing as important as oxygen in life. Oxygen was discovered already in 1773. Oxygen has been scientifically researched, especially in the field of medicine. It was discoverd how serious and partly life-threatening consequences lack of oxygen can cause in human body.

Oxygen is our metabolism. Our body receives most of it's oxygen through respiration. Oxygen is absorbed to blood circulation in our lungs. Hemoglobin can tie oxygen and take oxygen to the billions of our cells in our body. Our cells need oxygen to develop energy and warmth. The more energy our body uses, the more oxygen it needs. In addition to nutrition, we need oxygen sufficiently and continuously for our body to function and for every single cell in our body to keep healthy and functional.

Oxygen has also another important role in our body. Our immune system uses oxygen. Oxygen can destroy illness-causing electrones which live in an oxygen-free environment. This "destruction system" can destruct illness-causing baceria, viruses and mycosis.

The main oxygen suppliers are rain forests and sea plankton. Today, there is 30% less oxygen in the air than one hundred years ago. Increasing air polution, increasing rain forest cutting, polution of seas and rivers are some of the reasons for the decrease in oxygen content of the air.
