Blood Type A
Antigen: A
Anti bodies: B
Blood type B
Antigen: B
Antibodies: A
Blood type AB
Antigen: AB
Antibodies: None
Blood type O
Antigen: None
Antibodies: Anti A and Anti B
Rhesus Factor -/+ is determined?
By D antigen, if D antigen present the blood type is positive +
If the D antigen is absent, blood type is negative -
Blood type consider “Universal Recipient”
AB+ blood type
Blood type considered “universal donor”
O- blood type
Antigen
Specific protiens that play an important role in self recognition, which is the ability of the body to differentiate cells, recognize what is familiar or foreign.
Antibodies
Protiens made by immune system, able to recognize specific targets, found in blood plasma.
Agglutination
Occurs when wrong blood is given, causes a severe immune response, irreversible clotting, and hemolysis. A result of the bodys immune system attacking the antigens.
Rhesus factor
Known as the D antigen
First exposure not lethal
Most significant in pregnancy
Tunica Interna
-innermost layer
-single layer of simple squamos epithelium
-continous with endocardium, which lines inside of heart chambers
Tunica Media
-middle layer, latgest and bulkiest
-composed of smooth muscle
Tunica Externa
-outermost tunic of collagem and loose CT
-functions to support and protect the vessel
-serves as an ANCHOR
Arteries
-Higher blood pressure so arteries have thicker walls than veins
-Contains more tunica media
-Allows expansion and recoil to accommodate quick fluctuations in blood pressure caused by ventricular systole
Veins
-Low pressure vessels and therefore may have thinner walls
Capillaries
-Only one cell layer, tunica intima
