Active immunity - ANSWER -A form of acquired immunity in
which the body produces its own antibodies against disease-
causing antigens.
Toll-like receptors - ANSWER -recognize molecular patterns
unique to pathogens B-cells - ANSWER -Cells manufactured in
the bone marrow that create antibodies for isolating and
destroying invading bacteria and viruses.
Helper T-cells - ANSWER -Helper T-cells activate B-lymphocytes
and other Tcells in responding to the infected cells.
The Immune System: Adaptive - ANSWER -Respond to specific
antigens
Reaction: Cytotoxic T-cells kill pathogen
Prevention: B-cells produce antibodies
Activated by antigen and helper T-cells
Helper T-Cells Are activated by APC
,The Immune System: Adaptive Immunity con. - ANSWER -
Responds by remembering signature molecules, (antigens) from
pathogens to which the body has previous been exposed
Functional cells: Lymphocytes (T-cells and B-cells)
Antigen presenting cells digest pathogens and present it antigen
to signature "helper T cells"
When a helper T cell sees a cytotoxic T cell it produces
cytokines that activate the cytotoxic T-cell
The cytotoxic T-cell then searches out and destroys any cell that
contains the pathogen's antigen signature.
Helper T-cell also activates B-cells that recognized the
pathogens signature antigen
B-cell rapidly multiply into secretary cells called plasma cells
that can bind the antigen
If antigen levels subside, plasma cells stop making antibodies
and produce memory cells that remember the antigen.
Plasma Cells - ANSWER -Produce large amounts of antibody
(Immunoglobulins)
Adaptive - ANSWER -Able to change as need
Antibody - ANSWER -A blood protein that counteracts a specific
antigen
,Antigen - ANSWER -A toxin that stimulates an immune response
in the body
Antigen Presenting cell - ANSWER -A cell that displays foreign
antigens with major histocompatibility complexed on their
surfaces
Antimicrobial - ANSWER -A substance that kills or inhibits
growth of microorganisms with minimal damage to the host
B-cell - ANSWER -Cells that mature in bone marrow and make
antibodies in response to antigens
Barriers - ANSWER -A divider between parts of the body
Physical, cellular and soluble components that impede
pathogens from entering the body or multiplying
External Barriers - ANSWER -Include the physical barrier of the
skin and mucus secretions
Chemical Barriers - ANSWER -
Low pH salt
enzymes
, Cellular barriers - ANSWER -commensal micro-organisms
Passive Immunity EX - ANSWER -Rapid treatment for a
snakebite
Active Immunity Ex - ANSWER -Vaccination, in which the body
produces antibodies in response to the presence of an antigen
Immune System malfunction - ANSWER -Under activity of the
immune system can cause components to be ineffective
Ex: AIDs is caused by a virus HIV which infects helper t cells and
prevents it from activating cytotoxic T-cells and B-cells
Complement - ANSWER -The group of proteins in blood serum
and plasma that works with antibodies to destroy particulate
antigens
Dendritic cell - ANSWER -Antigen-presenting cells that process
antigen material and present it to T-cells
Immunoglobulin - ANSWER -An antibody
Innate - ANSWER -Inborn
