abo blood groups Flashcards
func of antibodies
defend against foreign particles
antibodies are produced by
lymphocytes
antibodies are found in
blood plasma (dissolved)
antigens found
on cell surface membrane

def of agglutination
clumping of particles caused by the binding of antibodies to their specific antigens
adv of agglutination
helps remove foreign particles
disadv of agglutination
blood clumps willblock/reduce transp of blood in narrow vessels reducing blood flow & oxygen supply
blood type =
antigens found on cell surface membrane
blood type a contains antigen _ and antibody _
a, b
blood type b contains antigen _ and antibody _
b, a
blood type o contains antigen _ and antibody _
no antigens, a & b
blood type ab contains antigen _ and antibody _
a & b, no antibodies
universal blood donor
o (no antigens on cell surface membrane)
universal blood acceptor
ab (no antibodies in blood plasma)
can a donor of blood type ab donate blood to someone with blood type a
no (ab has antigens a & b, a has antibody b; antigen b and antibody b will agglutinate)
can a donor of blood type b donate blood to someone with blood type o
no (b has antigen b, o has antibody a & b; antigen b and antibody b will agglutinate)
can a donor of blood type o donate blood to someone with blood type ab
yes (o is universal donor)
can a donor of blood type a donate blood to someone with blood type ab
yes (o is universal acceptor)
