Alyssa Villanueva immune system p.7
Major functions of the Lymphatic & Immune systems
lymphatic systems
secondary circulatory system, lymphatic vessels collect and carry away excess tissue fluid from interstitial spaces
immune system
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
Location of Lymphatic organs and their functions
thymus
functions
lobes that contain lymphocytes some mature into t cells / t lymphocytes
organs
thymus
lymph nodes
organs
cervial, supratrochlear, inguinal, thoracic, abdominal , axillary , pelvic
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
spleen
organs
the upper left abdominal cavity
functions
filters blood and removes damaged blood cells and bacteria
Purpose and examples of First, Second and Third line of defense
second line
fever, phagocytosis, immflamation, natural killer cells. ( faster response)
third line
cellular amd humoral immune systems
apc - helper t cells - b cells - killer t cells
apc - helper t cells - cytotoxins - plasma - antibodies
first line
skin and mucous membrane (barrier)
Humoral response and cellular response
humoral response
slower response and are the plasma and antibodies
cellular response
slower response and are the b and t killer cells
Innate(natural) immune defenses and Adaptive(acquired) immune defenses
adaptive 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
innate defenses
guard agaisnt many types of pathogens, quick res ponders, include : species resistance, mechanical barriers, natural killer cells, inflammation and fever
Antigens and antibodies
antibodies
a fraction of the plasma made by the cytotixic cell, has 5 different types LgG, LgA, LgM, LgE, LgD
antigens
can trigger an immune response, larger than a molecule, before birth the body makes and develops an inventory of self antigens
Artificial vs. Naturally acquired immunity
naturally
occurs after exposure to the antigen
artifically
vaccines without the person becoming ill
covid, flu
Passive vs. Active immunity
passive immunity
obtained by receiving antibodies
active immunity
obtained through antigen exposure
Cells involved in the immune system and their functions
apc
antigen presenting cell (a type of phagocyte)
cytotxins
gets bigger and turns into a plasma cell
killer t cells
cells that kill the pathogens
helper t cells
a cell that has antigens hanging off of them to connect to the apc
plasma
creates antibodies to go and kill the pathogens
macrophages
digest the pathogens
Disorders associated with the Immune system
hiv - aids
can be developed from std, blood transfusions or even dirty needles that enter into the skin
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
