Which of the following cells is an antigen presenting cell? Select all that apply
Dendritic Cell
Macrophage
Plasma cell
Natural Killer Cell
T helper Cell
These are markers on any pathogen that your immune system recognizes as "foreign" and creates memory cells to combat.
When Memory B cells see a pathogen they recognize, they quickly "mature" into these cells that produce antibodies:
Naive B Cells
Plasma Cells
Phagocytes
Mast Cells
Skin, mucous membranes, and phagocytes/ macrophages all parts of the:
Innate Immune System
Acquired Immune System
Secondary Response
Antigen Producing Cells
These cells find and kill your own cells that are infected with pathogens:
Cytotoxic T Cells
Memory B Cells
T Helper Cells
Antibodies
Antigen Presenting Cells (APCs):
Destroy any "invader" they encounter and present part of it to your immune system
Recognize antigens presented to them and become Memory B cells
Destroy your own cells that are infected w/ pathogens
Lie, cheat, and steal their way to success
T cells mature in the
thyroid gland
spleen
thymus
plasma cells
Both T cells & B cells are created in the
bone marrow
pancreas
thymus
spleen
Barrier defenses
can physically block pathogens from entering the body.
can chemically destroy pathogens before they can infect the body.
include nonpathogenic bacteria that outcompete pathogens.
All of the other answers are correct
Which of the following statements apply to the innate immune system?
It targets a specific pathogen.
It takes several days to work.
Consists of B and T cells.
It includes fever and inflammation.
An antigen is ______, whereas an antibody is_______.
a foreign substance to which lymphocytes respond; a protein that binds to antigens to eliminate them
a protein that is produced by lymph nodes in response to bacteria; a foreign protein that enters the body and causes an immune reaction
a hapten molecule that is quite complicated in shape; an enzyme that is produced by the thymus gland to neutralize antigens
produced by T-cells; produced by B-cells
Which B cells remain in the body for decades, allowing for a much more rapid specific response upon reinfection?
killer B cells
memory B cells
plasma cells
macrophages
Antibodies
are all exactly identical.
are produced by the innate immune system.
are cells that "eat" pathogens.
are highly specific to an antigen.

are destroyed by viruses.
are trained to recognize foreign antigens.
attack body cells.
consume pathogens.

Phagocytes:
deal with parasitic infections
involved in allergic reactions
eat and destroy pathogens
deal with specific invaders
Eosinophils:
attack and destroy large eukaryotic pathogens like fungi and helminths
are involved in inflammation and allergic reactions
engulf and destroy bacterial pathogens
activate T helper cells
produce antibodies
Basophils:
deal with parasitic infections
are involved in inflammation and allergic reactions
engulf and destroy bacterial pathogens
present antigens to activate T helper cells
produce antibodies
