How does Oxygen flow through our body?


The oxygen enters our body via our respiratory system but a significant percentage diffuses through the body via the skin pores.

 

The oxygen enters our blood via the alveoli coating the lungs surface. The lungs contain 300 millions alveoli that give an air/blood exchange surface of 100m2.

 

An adult body inhales around 1/2L air per respiration and performs 18 respirations per minute, which means that it inhales 13 m3 or 15 kg air per day! Since our body eats and drinks around 3kg food and fluid per day, it means that it ingests 5 times more air !!!

 

Oxygen represents 21% of the air. During one inhalation, around 25% of the oxygen enters the blood, which means that our body consumes 5% of the air it breathes or 750gr oxygen per day. One third is used by the brain !!! Consequently:

  • our brain uses 250gr oxygen per day
  • our body uses 500gr oxygen per day

Once the oxygen enters the blood, it is mainly transported by our Red Blood Cells, called “Erythrocytes” but a tiny part is dissolved in the blood fluid.

 

The heart pumps the blood, enriched with oxygen, through the 2 main “arteries”. One goes to the brain and the other to our tissues. Before reaching those organs, the arteries divide in tiny blood vessels called “capillaries”. In those capillaries, the oxygen (02) is transferred to the cells and the carbon dioxide (CO2), produced by carbon source metabolism in the cells, is transferred to the blood.

 

At the exit of each of those organs, the capillaries connect on one collector, called “vein”, that brings back the blood to the lungs in order to evacuate the CO2 and to load O2. Since the Red Blood Cells become larger when taking CO2, the blood is more viscous in the veins.

 

A healthy body has a dissolved oxygen concentration of 98%!

 

From 40 year’s age, the oxygen uptake starts decreasing and from 55 year’s age, the brain oxygenation starts degrading. Oxygen shortage is the cause of many illnesses

Some causes and consequences of oxygen shortage are reported in the following table:

 

Causes

Consequences

Poor physical fitness

Lung capacity reduction

High blood fat level

Red blood Cell aggregation

Blood viscosity increase

Body dehydration

blood viscosity increase

Stress

blood viscosity increase

Bad nutrition, stress

Narrowing & blocking of arteries (arteriosclerosis)

Alcohol

Inhibition of enzymes active in the respiratory pathway

Cigarette

5 to 10% less oxygen uptake

 

Complete oxygen shortage has the following consequences after a certain laps of time:

  • After 5”: function trouble
  • After 15”: consciousness loss
  • After 3’: brain cells damage
  • After 4’: brain cells death
  • After 30’: muscle cells death

Our Red Blood Cells have a lifetime of 100 days and reach their highest performance after 30-50 days.

 

Red Blood Cells possess “anion channels” that let permeate NAIs (Negative Air Ions). NAIs restore the natural small negative electric charge of the red blood cells, that repels each other and consequently prevents their aggregation. Consequently, the exchange surface for oxygen capitation increases.

 

In presence of excess of large proteins either deriving from tissue breakdown or from release of infectious material, the red blood cells tend to stick together by their maximum contact surfaces, becoming arranged like piles of coins. This reduces their oxygen uptake capacity.

 

NAIs inhalation prevents this phenomenon and instantly increase the oxygen content in the blood. A high oxygen content also increases the blood pH that must be ideally slightly basic, around 7.3-7.4.

When the blood is well oxygenised, not only the red blood cells contains oxygen but also the blood fluid. The very tiny blood capillaries, that are not accessible to red blood cells, are consequently better irrigated and surrounding tissues better oxygenized.

 

The oxygen uptake even more increase in presence of vitamin B1 en C en Magnesium.

 

In a poor oxygenated body, the blood contains more CO2 than in a good oxygenated one and is generally more viscous. Consequently, the heart must work at higher pressure. As reaction, the body strengthens the blood vessels, making them thicker and less elastic, a phenomenon called “arteriosclerosis”, the first cause of death!

 

At sea level, the Red Blood Cell concentration is around 4-5 Mio RBC/mm3. Since the oxygen concentration decreases with the altitude, the body reacts by producing smaller Red Blood Cells at higher concentrations. At 4000m high, they are smaller and their concentration is 2 times higher!

 

Conclusion:

 

A high oxygen content in our blood is crucial in order to:

  • - make the blood more fluid en consequently better irrigate the capillaries en reduce the blood pressure
  • - increase the blood pH
