a mature red blood cell

plasma protein that is converted to fibrin in the clotting process

a plasma protein containing the immunoglobulins that are responsible for immune responses

specific immunity produced by B cells that produce antibodies that circulate in body fluids

process of disease protection induced by exposure to an antigen

a localized response to an injury or to the destruction of tissues

Immunity that is present before exposure and effective from birth. Responds to a broad range of pathogens.

white blood cell

a small knob of tissue in the lymphatic system that filters lymph, trapping bacteria and other microorganisms that cause disease

mucosa-associated lymphoid tissue

the short-term immunity that results from the introduction of antibodies from another person or animal.

Liquid part of blood

The primary immune response of the body to antigen occurs on the first occasion it is encountered.

response when the antigen is encountered again the memory cells initiate a faster and stronger response

Organ near the stomach that produces, stores, and eliminates blood cells

(platelet) cellular fragment of megataryocyte; plays an important role in blood coagulation, hemostasis, and clot formation

An immune organ located near the heart. THe thymus is the site of T cell maturation and is larger in children and adolescents.
