Lymphatic and Immune System Flashcards
Granular, circulating leukocyte;
most abundant leukocyte in
blood.
neutrophil
Leukocyte that specializes in
phagocytosis
macrophage
Phagocytic leukocyte that
specializes in
antigen presentation
dendritic cell
Granular, circulating leukocyte
that targets
large, multicelled parasites
eosinophil
Granular, circulating white
blood cell.
basophil
Granular leukocyte that stays
anchored in tissues
mast cell
In a cell-mediated immune
response, cytotoxic T cells kill
body cells that have been
altered by infection or cancer.
NK cells kill ailing body cells
that cannot be detected
by cytotoxic T cells.
t cell
B lymphocyte. Leukocyte that
can make antibodies in an
adaptive immune response.
b cell
cell-mediated
t cell
antibody mediated
b cell
Immune cells that attack and eliminate harmful germs to
protect your body.
WBC
Proteins that bind to invaders and trigger their destruction.
antibodies
Chemical messengers that guide immune cells to specific tasks,
including regulating inflammation.
cytokines
A group of proteins that aids in defending against
invaders and promoting healing.
complement system
Small organs that filter lymph, removing waste and retaining
beneficial components like nutrients.
lymph nodes
Stores white blood cells, filters blood, and recycles old or damaged
cells.
spleen
Trap invaders like bacteria and viruses at the
entry points to your body.
tonsils and adenoids
Helps T-cells mature before they protect the body from
infections.
thymus
Produces blood cells, including white blood cells that
support the immune system.
bone marrow
Acts as a protective barrier to prevent germs from entering
the body.
skin
Detects and destroys germs in mucous
membranes throughout the body.
Mucosa-associated lymphoid tissue (MALT)
A fluid that drains from cells and tissues, carrying proteins, fats,
white blood cells, and harmful substances like germs and cancer cells.
lymph
Tubes that transport lymph throughout the body,
with one-way valves to ensure fluid moves in the right direction.
lymph vessels
Two main ducts that empty lymph into the bloodstream
at the subclavian veins.
collecting ducts
