(2) chapter 14 Flashcards
fluid leaves blood capillaries and may eventually be returned to blood through lymphatic vessels
lymph fluid
lymph from 3/4 of the body drains into the
thoracic duct
lymph from right upper extremity and the right side of the head drains into the
right lymphatic duct
enlarged pouch like structure in the abdomen that serves as storage for lymph
cisterna chyli
function of the _____ is to filter and clean lymph
lymph nodes
the lymphatic vessels that enter the lymph node are called
afferent
the single vessel leaving the lymph node
efferent
thymus is site of maturation for
WBC : T lymphocytes
thymus produces a hormone called
thymosin
tonsils located on each side of throat
palatine tonsils (the tonsils)
tonsils lie in posterior opening of nasal cavity
pharyngeal tonsils (adenoids)
tonsils near base of tongue
lingual tonsils
the signs of _____ are heat, redness, swelling, pain
inflammation
_____ kills threatening cells by drilling holes in on plasmas membrane which disrupt sodium and water
complement cascade
macrophages were originally _____ that migrated into the tissues
monocytes
the immunity that develops against polio after a polio vaccine
active artificial
the immunity that is given to fetus or newborn by mother
passive natural
immunity from injection of antibodies made by another individuals immune system
passive artificial
immunity that develops after a person has has a disease
active natural
cell that produces antibodies
B cell
cell that can develop into plasma cells (effector cells)
b cells
main cell involved in cell mediated immunity
T cell
main cell involved in humoral immunity
B cell
cell develops in thymus
T cell
cell moves to the site of the antigen and releases poison
T cell
cell divides into clones
B cell
cell that releases substances that attract macrophages
T cell
some cells develop into memory cells
B cells (can be T cells too)
tissue fluid
interstitial fluid
enters tiny blind ended tubes distributed in tissue spaces
lymph
located in clusters along pathways of lymphatic vessels
lymph node
perform biological filtration, where phagocytic cells alter contexts of filtered fluid
lymph nodes
upper left quadrant, lateral to stomach, protected by lower ribs
spleen
large network of reservoir veins and contains 1 pint of blood
spleen
accumulations of lymphocytes
white pulp
immunity is maintained by mechanisms that attack any irritant that threatens internal environment
innate immunity
innate immunity is also called _____ and considered first responders
nonspecific immunity
confers to GENERAL protection
non specific innate immunity
mechanisms of innate non specific immunity
mechanical & chemical barriers
inflammation
phagocytosis
complement
interferon
group of plasma proteins that are inactive enzymes
complement
proteins produced by cells after they become infected inhibits spread
interferon
B cell development
stem cells > immature B cells > activated mature B cell > memory and plasma cells
T cell development
stem cells > T cells > activated T cells > memory cells & effector cells
plasma cells in B cells responsible for
antibodies
effector cells in T cells responsible for
cytotoxic : kills
helper : trigger B and T
regulatory : stops reaction
humoral or antibody mediated
effects antigen to not harm body
cell mediated
resistance to disease
beaded appearance in vessels that maintain flow of lymph
lymphatic capillaries
inactive proteins make holes
complement
