Why red blood cells will clump together when different blood group is mixed together?

Answer 1

Each group has on its red blood cells specific antigens (Ag) that have the same name of the group. In the plasma (fluid of the blood) there are specific antibodies (Ab) that aren't harmful: they won't combine with the antigen present on the cells surface.
Group/ Antigen(s) /Antibody(ies)
A / A anti-b
B /B /anti-a
AB / A&B / none
O /none /anti-a & anti-b
So while mixing different groups the antibodies of one group will combine to the antigens of the other coz anti-a for example will bind with A.... that's why we'll have clumping of red blood cells

Answer 2

depending on the descriptions and my straightforward determination [typically biased] I in good structure AB and O with not one of the negatives although my self belief would properly be perceived for vanity sunlight - Aquarius Moon - Aries back bias from determination :/.... human beings pick what they pick and it ought to no longer be the actuality also purely 4 kinds... Dunno my actually blood type :/... yet i doesn't be shocked if it become AB or O... even though it particularly is 50% probability mixed If I had to in good structure each and each to an ingredient O = hearth or Water B = hearth + Sag + Pisces perhaps Water AB = Air or Earth certainly A = Earth... extremely Virgo.... also fastened signs and indications and Water signs and indications, probably fastened Water too those descriptions are somewhat too a lot of each signal and under no circumstances not person-friendly stressed right into a sparkling determination yet back like the previous question i'd say if someone had like a setup with maximum cancers sunlight Scorpio moon and many water with out Air and then "were given" [chosen] Sanguine... i'd be like duuuuuuuuuuuude.............BS!!!!!!!!!!... Liar!! compared to human beings i'm no longer politically splendid, i'm straightforward... And astrologers don't love operating backwards, or retaining a demonstration isn't any more suitable of "this, or 'that" ... I even haven't any pastime in doing that rather if it is the actuality....

Answer 3

its due to antigen antibody recation

Answer 4

antigens?
