Immune Headquarters
This primary lymphoid organ is responsible for producing lymphocytes.
What is red bone marrow?
This type of immunity is present at birth and responds rapidly to threats.
What is innate immunity?
Three defining characteristics of adaptive immunity are specificity, memory, and this type of cell response.
What is a lymphocyte response?
This type of immunity occurs when antibodies pass from mother to baby.
What is naturally acquired passive immunity?
Swollen lymph nodes usually indicate increased activity of these two immune cell groups.
What are phagocytes and lymphocytes?
These two organs are considered the primary lymphoid organs.
What are red bone marrow and the thymus?
These three processes are hallmarks of inflammation.
What are vasodilation, increased capillary permeability, and phagocytosis?
These lymphocytes are primarily responsible for antibody-mediated immunity.
What are B cells?
Vaccination is an example of this type of immunity.
What is artificially acquired active immunity?
In older adults, reduced activity of these cells may contribute to increased cancer risk.
What are natural killer (NK) cells?
These secondary lymphoid structures filter lymph and often become enlarged during infection.
What are lymph nodes?
These immune cells engulf and digest microbes.
These cells produce antibodies after B-cell activation.
What are plasma cells?
This feature of adaptive immunity allows a faster response during future exposures.
What is immunologic memory?
This field studies interactions among the nervous, endocrine, digestive, and immune systems.
What is psychoneuroimmunology?
Unlike lymph nodes, this organ filters blood and stores platelets and lymphocytes.
What is the spleen?
This antimicrobial protein helps limit bacterial growth by binding iron.
What is transferrin?
Another name for an antibody.
What is an immunoglobulin?
A gamma globulin injection would be an example of this type of immunity.
What is artificially acquired passive immunity?
A cytotoxic T cell's primary job is to do this.
vWhat is directly destroy infected or abnormal cells?
This acronym describes immune tissues located at common body entry points such as the tonsils and Peyer's patches.
What is MALT?
A patient has redness, warmth, swelling, and pain around a cut. This protective immune process is occurring.
What is inflammation?
These T cells help stop or suppress an immune response once the threat has been eliminated.
What are suppressor (regulatory) T cells?
A person develops immunity after recovering from chickenpox. This is an example of this type of immunity.
What is naturally acquired active immunity?
A student says, "The spleen and lymph nodes perform exactly the same job." This important difference would correct them.
What is "lymph nodes filter lymph, while the spleen filters blood"?
