take up plasma fluid that has been forced out of the
lymphatic capillaries
cardiovascular capillaries.
Interstitial fluid -> lymph capillaries -> larger lymph vessels ->
flow of lymph
venous blood
lymphatic vessels large vessels with valves, which collect and carry lymph
all lymphatic vessels enter thoracic duct or right lymph duct
venous circulation at the

both lower extremities
drains fluid from the right arm, right head and neck, and right

thoracic region
what are the lymphoid organs? lymph nodes, thymus gland, spleen, tonsils
filter lymph as is passes through the sinuses before entering
lymph nodes
general blood circulation
at the junction of lymphatic vessels. They tend to be grouped in
Where are lymph nodes
regions of the body and have a high concentration in the axilla
located?
region and groin region.
Interior structure of lymph divided into open structures called nodules that have
nodes lymphocytes and macrophages to clean the lymph.
where is the spleen located? left upper abdomen
Filters blood by removing old, defective RBCs or platelets and
function of the spleen?
removes debris, foreign matter and toxins from the blood
incoming: splenic artery
splenic blood flow
outgoing: splenic vein to hepatic portal vein
veins that carries blood that has been drained from the spleen,
hepatic portal system intestines, stomach, pancreas, and liver. Transports it to the liver
to be detoxified and cleaned.
Thymus secretes thymosin and thymopoietin
thymosin and thymopoietin enables T-Cells to mature so they can attack infected cells
a small group of lymphoid organs that gather and destroy
Tonsils
bacteria that is inhaled through air or food
crypts channels in tonsils that help trap bacteria and foreign matter
lymphoid tissue tissue in tonsils that destroys bacteria
uses chemical and physical barriers to prevent pathogens from
non-specific immunity entering the body. Generalized, rapid response that destroys a
large number of pathogens.
specific immune system protection against specific infections and diseases
How is the skin support innate It is difficult for pathogens to penetrate. It also produces sweat
immunity? and tears that allow for normal flora growth
how does sweat & tear by producing lactic acid which inhibits pathogenic bacteria
production allow for normal growth
flora growth?
nonspecific defense reaction to tissue damage caused by injury
inflammatory response
or infection
