blood and immunity Flashcards
blood transfusion
the transfer of blood from one person to another
antigens
specific proteins or sugars that are embedded in the membrane of red blood cells - used for ID
antibodies
specific proteins that are found in blood plasma (shields that fit with the antigens)
produced in responds of antigens
it binds to a CERTAIN antigen ( just like a lock and a key)
Blood Type A
This has A antigens on the red blood cells surface, and has the B antibodies in the blood plasma
Blood Type B
This has B antigens on the red blood cells surface, and antibodies A in the blood plasma
Blood Type AB
BOTH A and B-antigens on RBC surface,
and NO anti-A or anti-B-antibodies
Blood Type O
has NO A or B-antigens on BC surface, and
BOTH anti-A and anti-B antibodies
agglutination
clumping of red blood cells
Blood typing
the blood types must match or else blood clots will be formed and the patient will die.
Rhesus Factor also known as Rh
another important group of antigens that can be found in the membranes of RBC
Rh +
antigen present
Rh -
antigen NOT present , however most people with Rh - will not have an antibody present unless it’s transferred or pregnancy
Red blood cells
RBC only, from a compatible donor This is usually what we talk about in terms of donors/recipients
Plasma
plasma only, from a
compatible donor Plasma is the opposite of red cells…AB+ is the universal donor because their plasma
won’t have any anitbodies
Functions of Blood
Transport, Homeostasis and Protection
