Coagulation

Clotting of blood

Thrombus

A clot that develop in an unbroken blood vessel

Embolus

Thrombus that breaks away from the vessel wall

Antigen

A toxin/foreign substance that induces immune response in the body and mounts a defense against it

Antibodies

“The recognizers” a blood protein produced in response that attract antigens

Agglutination

Bacteria or blood cells clump together

Hemolysis

Rupture of red blood cells

Blood Type

A classification of blood, based on the presence and absence of antibodies on the surface of RBC’s
