basophil

eosinophil

lymphocyte

monocyte

neutrophil

Neutrophils

"First responders" to injury, carry out phagocytosis

Lymphocytes

Production of antibodies; some carry out direct cell killing

Monocytes

Carry out phagocytosis; take over for neutrophils at an injury site

Eosinophils

Fight parasitic worms; also involved in inflammation reaction

Basophils

Involved in inflammation reaction; release histamines and heparin

Antigen

A protein that, when introduced in the blood, triggers the production of an antibody

Antibody

A protein that acts against a specific antigen

ABO blood groups

Genetically determined classes of human blood that are based on the presence or absence of antigens A and B on the surface of red blood cells. The ABO blood group phenotypes, also called blood types, are A, B, AB, and O.

Rh blood group

Genetically determined class of human blood that is based on the presence or absence of antigen D on the surface of red blood cells. The Rh blood group phenotypes, also called blood types, are + and -.

Agglutination

Clumping of red blood cells by antibodies when an improper blood type is introduced in a transfusion

hemolytic disease of the newborn

This disease occurs in the fetus if the fetus is Rh+ while the mother is Rh-, and if the mother has been sensitized to the Rh antigen after a previous pregnancy
