,What is the primary definition of immunology?
The study of the immune system, which protects the body from infections, foreign
substances, and diseases.
What are the two main branches of the immune system?
Innate (nonspecific) immunity and Adaptive (specific) immunity.
Which branch of the immune system is present from birth and responds quickly
to pathogens?
Innate (nonspecific) immunity.
What are three examples of physical or chemical barriers in the innate immune
system?
Skin, mucous membranes, stomach acid, and enzymes in saliva/tears (e.g., lysozyme).
Which cells in the innate immune system are responsible for phagocytosis?
Neutrophils and macrophages.
What is the primary function of Natural Killer (NK) cells?
To attack infected cells.
what is opsonization?
complement system; coating pathogens to make them easier for immune cells to eat
Which branch of the immune system develops after exposure to pathogens or
vaccines and provides long-term memory?
Adaptive (specific) immunity.
What are the two main components of adaptive immunity?
Humoral immunity (B cells and antibodies) and Cell-mediated immunity (T cells).
What is the role of B cells in the immune system?
To produce antibodies (immunoglobulins) to neutralize pathogens.
What are the two types of T cells and their primary functions?
Helper T cells (CD4) stimulate the immune response; Cytotoxic T cells (CD8) kill
infected or abnormal cells.
Where do T cells mature?
The thymus.
What is the function of the spleen in the immune system?
It removes old red blood cells and filters pathogens from the blood.
How does active immunity differ from passive immunity?
Active immunity is acquired through infection or vaccination and creates memory cells;
passive immunity is the transfer of antibodies (like colostrum) and provides only
temporary protection.
What is a hypersensitivity reaction?
An overreaction of the immune system, such as allergies or anaphylaxis.
What is an autoimmune disease?
A condition where the immune system attacks the body's own cells, such as Immune-
Mediated Hemolytic Anemia.
What is an immunodeficiency?
A state of weak or absent immune responses, such as Feline Immunodeficiency Virus
(FIV).
Why are vaccinations important in veterinary medicine?
They stimulate adaptive immunity to protect animals against specific diseases.
, What is the role of bone marrow in the immune system?
It is the site of blood cell production, including white blood cells.
What is the function of lymph nodes?
They filter pathogens and activate immune responses.
List three laboratory tests a veterinary technician might assist with regarding
immune function.
CBC, antibody titers, and immune function tests.
Immunology 3
What is the primary function of the innate immune system?
To provide immediate defense against infections and tissue damage.
What are the main components of the innate immune system?
Chemical mediators, cytokines, acute phase reactants, and cellular components like
neutrophils, macrophages, and NK cells.
What initiates the acute inflammatory response?
The release of inflammatory mediators by resident cells in response to infection or
tissue damage.
Which cells are the dominant players in acute inflammation?
Neutrophils.
What is the normal range of neutrophils in the blood?
4,000 to 10,000 cells per microliter.
What is the lifespan of a neutrophil?
About 6 hours, longer if activated.
What are the two types of granules found in neutrophils?
Specific granules and azurophilic granules.
What do specific granules in neutrophils contain?
Enzymes such as lysozyme, collagenase, and elastase.
What is the role of granulocyte colony stimulating factor (G-CSF)?
It stimulates the production of neutrophils from the bone marrow.
How do monocytes differentiate into macrophages?
Monocytes recruited into tissues from the blood differentiate into macrophages.
What activates macrophages to destroy microbes?
Microbial recognition through TLRs or key cytokines such as IFN-γ.
What are classically activated macrophages also known as?
M1 macrophages.
What is the process by which neutrophils and macrophages destroy microbes?
Engulfment followed by killing in the phagolysosome.
What are reactive oxygen species (ROS) and their role in immune response?
They are antimicrobial molecules produced by NADPH oxidase to kill engulfed
microbes.
What is Chronic Granulomatous Disease (CGD)?
A condition caused by a mutation in the NADPH phagocyte oxidase enzyme complex,
leading to recurrent infections.
What is the role of macrophages in the adaptive immune response?
They present antigens to T cells.
What do mast cells release during the innate immune response?
Histamine, which causes vasodilation and increased permeability of blood vessels.
