The lymphatic system absorbs lipids and
other substances from the digestive tract
through lymphatic vessels called
lacteals
The lymph passing through these lymphatic vessels appears
white because of its lipid content and is called
chyle
The lymphatic organs include
the tonsils, the lymph nodes,
the spleen, and the thymus
removal of the spleen
splenectomy
the ability to resist damage from pathogens
immunity
the ability
of adaptive immunity to recognize a particular substance
specifity
the ability of adaptive immunity
to “remember” previous encounters with a particular substance
memory
prevent pathogens and chemicals from entering
the body in two ways
Physical barriers
molecules responsible for many
aspects of innate immunity.
chemical mediators
is a group of more than 20
proteins found in plasma.
complement
are proteins that protect the body
against viral infections.
interferons
the ingestion and destruction of
particles by cells called phagocytes
phagocytosis
are monocytes that leave
the blood, enter tissues, and enlarge about fivefold
macrophages
which are derived from red bone marrow, are motile
white blood cells that can leave the blood and enter infected tissues
basophils
which are also derived from red bone marrow, are
nonmotile cells in connective tissue, especially near capillaries.
mast cells
Natural killer (NK) cells
lymphocyte
is an inflammatory response confined to a specific area of
the body.
local inflammation
an inflammatory response that is
generally distributed throughout the body
systemic inflammation
