Do you know the different blood groups? And do you know which blood group you have? Most Germans have no idea what group it belongs to is the most important substance in your body. This can be fatal.
On the question of the blood group, must fit the most. Only a few know you, even though it could save your life. The same applies for accident victims. It is known that the blood group of the Victim has help the paramedics and the Doctors to organize as quickly as possible, a suitable blood donation, because not every blood group is suitable for everyone.
In principle, a simple System
Is used to determine the blood group by the genes you inherited. The so-called AB0 (Null)-System divides human blood into four different blood groups: A, B, and 0. In the case of a blood donation, there are unique mappings. Donor blood and recipient blood are not compatible, this can lead to clumping and even fatal consequences. To know your blood group, so it can be vital.
Who can with whom?
With 43 percent of blood group A is most frequently in Germany. In second place is blood group 0 blood group can be donated to all of the receiver. Blood group B have eleven percent of the population in Germany and just five percent.
In the case of blood donations, the relevant blood groups have to match
Blood group 0 is very sought after. Who has group blood, is a donor for all the question, then, is the universal donor. Blood group AB, however, is universal recipient, can receive any blood group. Before the discovery of the blood groups it was mostly coincidence, if a Transfusion without complications went.
Anti-bodies and antigens
An important factor is the antibodies. These are proteins present in Plasma. They are part of the natural defenses of the body, identify foreign substances such as bacteria and alert according to the immune system. In the case of the blood groups, this means that antibodies produced against any foreign blood cells, this is detected and combated.
Also antigens play a crucial role. The protein molecules located on the surface of red blood cells. People with blood group A have on the erythrocyte surface is the Antigen A. In group B, according to the Antigen B is present. In the case of blood group AB red blood cells, none have both antigens, blood group 0.
The immune system forms according to the lack of antigens and antibodies. People with blood group A have antibodies against B, and Vice versa. People with blood group AB have no antibodies. In the case of group 0, both antibodies against A and against B are available.
Rhesus factor positive or negative?
The second most important blood group system the AB0 blood group system is the Rhesus System. The rhesus factor is a “D Antigen” on the red blood cells. Who has this Antigen is rhesus-positive. Who has not this Antigen is rhesus-negative. Similar to the blood group rhesus-negative people for antibodies against rhesus form-positive blood. These factors are important in the case of a blood transfusion.
About 85 percent of the European population are rhesus positive. Rhesus-negative blood is the blood donation rather scarce.
Karl Landsteiner discovered the different blood groups
The discoverer of the blood groups
We owe. the blood groups of the pathologists, hematologists, and Serologen Karl Landsteiner He was on 14. June, 1868, was born in Vienna on his birthday of world blood donor day reminds every year. Landsteiner discovered the so-called AB0 System of blood groups in 1900. For this, he received in 1930, the “Nobel prize for physiology or medicine”. His discovery was a milestone in medicine.
The world blood donor day also aims to draw attention to the fact that blood donors are urgently sought. Because too few people sign up for it. How important blood donations are, is many clear when you need an urgent blood transfusion.

Blood: iridescent, almost like a rainbowGreen Blood
The toxic green blood and the smooth lizards from new Guinea, is the reason for this gallery. His Granny Smith Apples reminiscent of color continues in the muscles, bones, and in the oral cavity of reptiles. To blame green bile, which is superimposed on a high concentration of the really red color of blood cells. This does not mean, of course, that Granny Smith would be Apples poisonous. Good Appetite.

On Kraken, many a nobleman is likely to be jealous, because you have kings of nature, something to which, and the princes are so fond of called blue blood. The copper binding in the octopus blood (but also in the case of lobsters and other ink-fish) of oxygen. In the case of us iron takes over this function and the colors, as we know, red.

Blood: iridescent, almost like a rainbowWhite Blood
The fish here, the krokodilei fish is, the color in the blood completely. Through his veins a clear fluid flows, because of the polar inhabitants has no haemoglobin (red blood dye) still Hemocyanin (blue blood dye). Why? The cold water of his homeland stores much more oxygen than warmer water. Therefore, the fish needs to be simply no active oxygen carrier.

Now it is a bit tricky. This little animal here, a sea cucumber is green, your blood is more yellow. And, this is impossible to explain not so easy to. Chemically speaking, the so-called Vanadium, and the Protein that binds this Element is located. As far as we know, it has no special influence on the oxygen transport in the blood. Nevertheless, it is there.

Logical it is again in this color variant of the blood. Purple it is, if Hämerythrine are in the game, which act as oxygen transporters. They do but only in the case of invertebrates in the water, as this injection worm. Oxygen docks, a violet, sometimes pink color.

Blood: iridescent, almost like a rainbowRed Blood
So now the man. We also have clear, red blood. Located on the iron, the hemoglobin, we know. If this protein oxygen attaches, then the blood is red. By the way, this is also true for all mammals.

Blood: iridescent, almost like a rainbowMr. Spock
And what is Mr. Spock doing in this list? The Vulcan looks like a man, but it’s not like the Star Trek connoisseur knows. His juice of life is based not on iron but on copper, the thought of the authors of the series so. Therefore, it would have to be blue, like an octopus (see image 2).
