chapter 16 Flashcards
the bodys ability to recognize and defend itself against specific pathogens and their products
adaptive immunity
an adaptive immune response that acts against one particular pathogen or molecular shape on pathogen
specificity
the specific pathogen causes or induces immune response it is off until turned on
inducibility
once induced cells of an adaptive immune response proliferate to form many identical cells
clonality
the adapative immune response will not attack host cells
unresponsiveness to self
immunological memory for specific pathogen
memory
adaptive response involves
b and t lymphocytes
in the red bone marrow and are a stem cell that gives rise to all types of blood cells
hematopoiteic cells
arise and mature in red bone marrow
b lymphocytes
arise in red bone marrow mature in the thymus
t lymphocytes
an immune response controlled and carried out by t cells
cell-mediated response
used against intracellular pathogens, a virus inside of a cell
t cells
an immune response controlled and carried out by b cells
antibody or humoral immune response
used against extracellular pathogens and toxins
b cells
a protective protein secreted by descendants of b cell that recognizes and strongly binds to a unique part or biochemical on a pthogen called an antigen
antibody
lymphatic vessels with lymph and lymphatic organs
lymphatic system
a colorless fluid similar in composition to blood plasma, leaks out of blood vessels into surrounding intercellular space
lymph
contain b and t lymphocytes that screen fluid for pathogens
lymph nodes
contains a web of passages where lymphocytes mount specific attacks against pathogens
inner medulla
b cells replicate in an
outer cortex
