2 blood types, blood transfusion and tissue and organ transplantation
take one part of an organism and place it on another location on the same organism
autograft
transplant between identical twins
isograft
univeral donor
o
transplant between same species
allograft
relative frequency of blood types % O A B AB
47 41 9 3
three different gene variants, which are dominant
A B O A and B are dominant
two types of antigens that stimulate blood transfusion rxns
OAB system and Rh system
if A + blood is transfused into a A - person what happens
Rh negative, this person can develop antibodies slowly in 2-4 months
__ is important during pregnancy and to prevent transfusion reactions
Rh typing
on the surface of red blood cells causes most blood transfusion reactions
a b antigens
universal recipient
ab+
antibodies in the plasma and are usually igG and igM
agglutinins
blood typing happens when you separate rbc and they are diluted with saline, treated with agglutinin sadsjfgnfdgj
agkdfgj
occurs when blood is transfused from one person to another with person who has a diff blood type it results in agglutination and hemolysis of rbc
blood transfusion reaction
A B O
blood types
used to identify donor blood so that matching the recipient can decrease the likelihood of transfusion reactions
blood typing
disease of fetus and newborn
erythroblastosis fetalis
there are six hla antigens that commonly cause
graft rejection
how can we prevent graft rejection
tissue typing (match of 6 hla proteins, very difficult)
the presence or absence of agglutinogens influence blood
type
transplant between different species
xenograft
