Immunity part 2 blood groups Flashcards
In humans, blood type is classified in 2 ways..
ABO group and Rhesus Group
ABO grouping is a test to classify blood type. The test looks like this, list the antigen what blood type displays..
Blood type A individuals display..
Blood type B individuals display..
Blood type AB individuals display..
Blood type O individuals display..
Blood type A individuals display A antigens
Blood type B individuals display B antigens
Blood type AB individual display AB antigens
Blood type O individuals display NO antigens
Rhesus grouping ( Also known as Rh grouping ) is a test to determine Rhesus antigens in individuals blood type. List what they display..
Rh (+) positive individuals display..
Rh (-) negative individuals display..
Rh (+) positive individuals display Rhesus antigens
Rh (-) negative individuals display NO Rhesus antigens
In ABO grouping, not only do our red blood cells presents various antigens depending on our DNA, antibodies against other blood type are produced by our white blood cells. This makes your unique blood type incompatible with..
other blood types
What makes your blood not compatible with other blood types?..
Our white blood cells produce antibodies that are against other blood type
In ABO grouping, blood type A individuals display A antigens and produce antibodies against..
B antigens. Therefore if blood type A individual needs blood, they will need type A blood or type O
in ABO grouping, blood type B individuals display B antigens and produce antibodies against..
A antigens. Therefore if blood type B individuals is in need of blood, they will need type B blood or type O
In ABO grouping, blood type AB individuals display both A and B antigens and does not produce antibodies against either antigen. Therefore, blood type AB individuals can..
Take blood type A, blood type B, blood type AB and blood type O
In ABO grouping, blood type O individuals do not display any antigens, but produces antibodies against A and B antigens. Therefore, blood type O individuals can..
only take blood type O. However, blood type O can be taken by all types (Blood type A, blood type B, blood type AB) they can not take others and ONLY take type O
In a blood type graph, when blood type is mixed with a blood type they DO NOT GO TOGETHER, they group to them. The grouping of these blood type is called..
Agglutination
AB + blood type individuals have all 3 types of antigens on their red blood cells, therefore they do not produce any antibodies to go against these antigens. As a result, they..
can receive any blood type from any donor. this is a universal recipient
What is a universal recipient and what blood type?
A universal recipient is type AB + blood
In Rh grouping, list the steps when an Rh negative woman ( no Rhesus antigen ) wants to have a baby with a Rh positive man ( has Rhesus antigen )
- The man with the Rhesus antigens injects the semen into the Rh negative woman fetus
- Cells from Rh positive fetus enter the woman’s blood stream
- Woman form sensitized antibodies to fight Rh positive blood cells
- When Rh positive makes an appearance again (next pregnancy), the maternal antibodies attack the Rhesus antigens
In Rh grouping, list the steps when an Rh negative woman ( no Rhesus antigen ) wants to have a baby with a Rh positive man ( has Rhesus antigen )
- The man with the Rhesus antigens injects the semen into the Rh negative woman fetus
- Cells from Rh positive fetus enter the woman’s blood stream
- Woman form sensitized antibodies to fight Rh positive blood cells
- When Rh positive makes an appearance again (next pregnancy), the maternal antibodies attack the Rhesus antigens in red blood cells
O- type blood individuals have no antigens present on their red blood cells so they can..
donate to individuals with all blood types. this is called a universal donor
