Major functions of the Lymphatic & Immune systems
Location of Lymphatic organs and their functions
lymphatic systems
immune system
Purpose and examples of First, Second and Third line of defense
Humoral response and cellular response
Innate(natural) immune defenses and Adaptive(acquired) immune defenses
Antigens and antibodies
Artificial vs. Naturally acquired immunity
Passive vs. Active immunity
Cells involved in the immune system and their functions
Disorders associated with the Immune system
antibodies
antigens
second line
third line
first line
skin and mucous membrane (barrier)
fever, phagocytosis, immflamation, natural killer cells. ( faster response)
cellular amd humoral immune systems
apc - helper t cells - b cells - killer t cells
apc - helper t cells - cytotoxins - plasma - antibodies
adaptive defenses
innate defenses
slower process, respond to certain pathogens, toxins and or metabolic products, thrid line of defense against pathogens, include both cellular and hum oral immune response
guard agaisnt many types of pathogens, quick res ponders, include : species resistance, mechanical barriers, natural killer cells, inflammation and fever
thymus
lymph nodes
spleen
organs
funtions
immune serveillance: monitor body fluids; preformed by lymphocytes and macrophages
filter lymph : remove bacteria and cellular debris before lymph returns back into the blood
lymphocytes : aattack biruses bacteria and parasitic cells that enter a lymph node
lymphocyte products : whore lymph nodes are also centers
cervial, supratrochlear, inguinal, thoracic, abdominal , axillary , pelvic
functions
organs
lobes that contain lymphocytes some mature into t cells / t lymphocytes
thymus
organs
functions
the upper left abdominal cavity
filters blood and removes damaged blood cells and bacteria
secondary circulatory system, lymphatic vessels collect and carry away excess tissue fluid from interstitial spaces
where all cells are able to fight and protect the body from diseases that have entered into the blood stream or from any holes that may have appeared in or on the body
hiv - aids
can be developed from std, blood transfusions or even dirty needles that enter into the skin
passive immunity
naturally
artifically
vaccines without the person becoming ill
occurs after exposure to the antigen
a fraction of the plasma made by the cytotixic cell, has 5 different types LgG, LgA, LgM, LgE, LgD
can trigger an immune response, larger than a molecule, before birth the body makes and develops an inventory of self antigens
covid, flu
apc
cytotxins
killer t cells
helper t cells
plasma
humoral response
cellular response
macrophages
a cell that has antigens hanging off of them to connect to the apc
cells that kill the pathogens
antigen presenting cell (a type of phagocyte)
gets bigger and turns into a plasma cell
creates antibodies to go and kill the pathogens
digest the pathogens
auto immune disorder
may result from viral infections, faulty t cell development or reaction to a non self antigen that closely resembles a self antigen
type 1 (insulin dependent) beta cells in the pancreas which produce insulin are destroyed by autoantibodies
active immunity
obtained through antigen exposure
obtained by receiving antibodies
slower response and are the plasma and antibodies
slower response and are the b and t killer cells
