Oxygen in the blood and its importance for the human body

How does oxygen get into the blood?

• The vital oxygen enters through the air we breathe body. First, the oxygen is directed into the lungs. Here it collects in the microscopic alveoli, which are connected to the blood circulation via tiny blood vessels (capillaries).
• The important gas exchange takes place in the alveoli. The alveoli give off the accumulated oxygen to the blood and on the other hand absorb the CO2 accumulated in the body. This is now exhaled.
• In the blood, the red blood pigment hemoglobin is responsible for binding oxygen to the blood.
• The oxygen-enriched blood now flows through the whole body, there to supply the Organs remove oxygen and collect the CO2 produced in the body to return it to the lungs submit. The whole thing is an endlessly continuing cycle, without which man could not live.

• Amazing but true: the contact area between the alveoli and the blood vessels is 120 square meters.


How does oxygen get into the muscle?

In order to move, you need muscles that can contract. To the …

What does the human body need oxygen for?

• Oxygen is an important part of many processes in the body. These include, for example, the growth and activity of the organs.
• Just as the entire body breathes in oxygen through the lungs, so do the individual organs. Of course, they do not take in oxygen through the lungs, but rather through tiny blood vessels called capillaries.
• This process is known as cell respiration and triggers a reaction in the organs that releases the bound nutrients from the food and makes them usable for the organs.
• A permanent lack of oxygen in the blood can considerably restrict the body functions and lead to a general loss of strength, poor concentration, an undersupply of the cells, etc. to lead.
• The causes of a lack of oxygen are usually heart or lung diseases, which require regular monitoring by a doctor. However, a lack of oxygen can also be promoted by an incorrect, excessively acidic diet, as the acid in the blood blocks hemoglobin.
• An undersupply of the organs by oxygen can very easily in everyday life by too little Fluid intake is triggered as the blood thickens and the nutrients and oxygen now increase more slowly brings the organs. This condition is corrected simply by drinking more.

How can the oxygen level in the body be influenced?

• One way to increase the oxygen level in the blood is to stay at high altitude for a long time. This may seem surprising at first, since the oxygen content in the air is lower here.
• The human body reacts to this phenomenon, however, with an increased production of hemoglobin, which is, so to speak, the means of transport for the oxygen in the blood. In the end, the same amount of oxygen is released into the blood with each breath, although the amount in the air is lower.
• When a person with such an increased number of red blood cells is back in their usual environment, at least they have time long, there is still an increased amount of hemoglobin in the blood thus absorbing a higher amount of oxygen than is normally the case were.
• Above all, high-performance athletes take advantage of this phenomenon, who can naturally increase their willingness to perform. A regular stay in the mountains is also recommended for people with health problems, as a high oxygen level in the blood is important for a functioning immune system.
• However, people with normal lungs (excluding high-performance athletes) shouldn't do more every day than 1000 m difference in altitude, as the body needs a little time to process the red blood cells to produce.
• Taking long, deep breaths, the body receives more oxygen with a single breath than with conventional breathing. If you do a lot of sport regularly, you will achieve the same effect and that permanently in everyday life. And due to the increased lung volume, more oxygen is absorbed overall.
