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
