|
functions of the lymph system
|
-drain interstisial fluid
-transport dietary fats -protect against invasion -remove waste proteins from the plasma that the venule can't take in |
|
|
lymph and its' function
|
fluid
to - transport nutrients -transport waste -protect the body from invasion |
|
|
flow of lymph is maintained….
|
primarily by the contraction of skeletal muscles that compress lymphatic vessels and force lymph toward subclavian veins
|
|
|
lymph tissue
|
leukocytes (white blood cells)
|
|
|
lymph vessels (4)
|
-lymph capillaries
-lacteals -lymph vessels -lymph duct |
|
|
lymph capillaries
|
exist at cell level, between cells, have valves to make sure lymph doesn't flow back
|
|
|
lacteals
|
only in small intestine, transport fat back into blood
|
|
|
lymph vessels
|
like smaller veins that bring lymph from tissue back to the heart
|
|
|
lymph duct
|
largest vessels -thoracic and right lymphatic ducts
|
|
|
lymph nodes
|
filter lymph by removing foreign substances and stimulate production of lymphocytes
|
|
|
proliferation
|
rapid, repeated, reproduction
|
|
|
secondary lymphatic organ that acts as a blood resevoir, destroys worn out RBCs, filters blood, and is the site of B cell proliferation
|
spleen
|
|
|
red bone marrow
|
primary lymphatic organ that produces B cells and pre T cells
|
|
|
thymus
|
primary lymphatic organ that is the site for processing and maturing T cells
|
|
|
lymph is pumped through the body
|
skeletal muscles- contract to compress lymphatic vessels and force lymph toward the subclavian veins which dump into the heart
-respiratory pump- breathing create pressure between the two ends of the lymphatic system |
|
|
lysomsomes
|
enzymes in sweat capable of breaking down cell walls of bacteria
|
|
|
phagocytes
|
White blood cells
|
|
|
nonspecific resistance to disease
|
our bodies first response to invaders
|
|
|
specific resistance (immunity)
|
involves the production of a specific lymphocyte or anitbody against a specific antigen
|
|
|
active immunity
|
you get sick naturally or artificially with vaccinations
|
|
|
passive immunity
|
you get sick naturally thru trnasfers in the fetus or artificially through oral or intravenous antibodies
|
|
|
antigen
|
the foreign invader that provokes and immune response
|
|
|
antibody
|
a protein that combines specifically with antigen that triggered its production and kills it
|
|
|
autoimmune diseases (9)
|
-AIDS
-Lou Gehrigs -Cancer -Hodgkins -Lupis -Chronic Fatigue -Fibromyalgia -rhematoid arthritis -lymes disease |
|
|
cycle of flow of lymph
|
arteries-bllod cappilaries-interstitial spaces-lymphatic capillaries-lymphatic vessels-lymphatic duct-subclavian veins-back to arteries
|
|
|
T cells
|
to destroy foreign invaders directly
|
|
|
B cells
|
develope antibodies to destroy foreign invaders if T cells can't do it directly
|
|
|
with inhilation lymph flows from the abdomen to
|
the thoracic region
|
|
|
WBCs (2 kinds)
|
microphages and macrophages that go to area and eat up damaged tissue and invaders
|
