The Duffy blood group system is a method of categorizing human blood types through the Fy antigens found on the surface of red blood cells. There are 4 of such blood types.
There are many types of blood group systems. ABO and Rh being the two main systems... Others are: Kell, Kidd, Duffy, etc. (there are many more)
Yes. You have MN system of blood group in humans.
The ABO blood group system was discovered in 1900 by Karl Landsteiner. The AB blood group was discovered by Von Decastellor and Sturli in 1902.
explain co-dominance selecting the example of ABO blood group system
Basic imunology principle; if you wanna detect specific antibody, you should have a specific antigen to detect it. The other blood group system considered as minor blood group and of course the major one is ABO and Rh system. Antibodies from other blood group such as MNSs, P, Mia, Kidd, Kell, Duffy, Lewis, Diego etc. might cause hemolytic transfusion reaction as well in case of it's catagories in IgG class. From basic imunology princeple, known cell, Standard cell O can be used for detecting antibodies from other blood group systems. The main reason of using O cell for detect other blood group is.. there're no A-Ag and B-Ag on red cell. The process of anti human globulin test (Indirect coombs test) could be perform between serum sample and standard o cell to detect antibodies form other blood group systems.
In the ABO blood group system, a person's immune system naturally creates antibodies to the antigens that it lacks. Group A people have the A antigen, so they will make Anti-B. Group B people have the B antigen, so they will make Anti-A. Group O people do not have A or B antigens, so they make both Anti A and Anti B. Group AB people have both A and B antigens. They do not have antibodies in this blood group system. So, the short answer to your question: B and O people will both have Anti-A in their blood.
MN blood group codes for antigens M and N on red blood cells . and ABO blood group does the same by coding A B AND i antigen on red blood cells. but as MN blood group do not illustrate strong immunity so they are ignored in regular blood transfusions . while ABO blood groups are taken in consideration as the give strong immunological reactions
The urinary system takes the waste from your blood and excretes it when 'nature calls'.
I assume what you are talking about is D antigen in Rh (Rhesus) blood group system. Rh blood group system is the most important blood group system after ABO blood group system (i.e. type A (AA, AO), type AB, type B (BB, BO), type O (OO) ). The Rh blood group system consists of 50 defined blood-group antigens and the 5 antigens D, C, c, E, and e are the most important. The commonly-used terms Rh factor, Rh positive and Rh negative refer to the D antigen only. Rh factor (Rh- and Rh + depending on D antigen neg/pos) is important for blood transfusion and prevention of hemolytic disease of the newborn or erythroblastosis fetalis (basically the baby and mom have different blood type - Rh- and Rh+ and cause severe immune response - fatal to the newborn)
It depends what blood group or system you are interested in. The major blood groups are the ABO and Rh system. In addition to these, there are approximately 30 other blood groups/systems of importance in immunohematology.
Blood groups are dertermined on the surface of the red blood cells and they have nothing to do with our immune system.
Blood group O has both a and b antibodies, therefore receiving blood from blood group A, the A-antigens will agglutinate with the b-antibodies of the person with blood group O. Receiving blood from blood group B will also cause agglutination of its b-antigens and the blood group O's a-antibodies.
