what leukocyte will be the 1st to responf to a diesase
which wbc will secrete lysomal enzymes(digestive enzymes
what wbc forms pus
neutrophil from dead neutrofragments and dead bacteria
which leukocyte will increase during an allergic reaction?
which wbc will be involved in antibody immunity
which wbc will decrease inflammation and what compounds
eosinophils using hisaminase
what wbc wbc will leave blood and become macrophage
what wbc will attract fibroblasts
monocytes(helps isolate the infection
antigen presenting cell
what leukocyte would perform immunological surveillence
wbc invoved in cellular immunity
lymphocyte t cells
what wbc will fight parasitic infections?
what wbc will be elevated in someone with a cronic infection
which wbc will attack antigen antibody complexes

neutrophil (produceh202 and attacks membrane of cell
how do lymphatic capularies differ from blood capillaries
are a dead end vessel. endothelial cells overlap.basement membrane incomplete r none exsistant.larger diameter.thinner walls.one way flow. lower resistance -lots of valves musclar compressin respiratory pump
pressure in lymph and intersitual
If pressure in the intersitual fluid >pressure In capillary cells separate and fluid comes in. that fluid becomes lymph.
If pressure intestitial<capillary pressure,cells do not separate-nothing comes in
is a lymphatic capillary that absorbs dietary fats in the villi of the small intestine.
how lymphatic capillaries merge into large lymphatic vessels
The trunks merge into 1) right lymphatic duct 2)thoratic duct*old lymph back to venous circulation*(as we are doing this we r making new lymph) the excess 3 liters from the venous system goes to the lympatic system causing lymph.
what is the purpose of lympatic ducts?
1)filter looking for pathogens
2proliferation of lymphocytes
Lymphatic vessels. Merge to
Lymphatic trunks then merge to right lymphatic duct and thoracic duct brining back to venous circulation
Where does lymph come from
Whats the purpose off lymphatic ducts and how do they drain
Bring old lymph back to venous circulation
How does primary differ from secondary lymphatic organ?
Primary where cells become immunocommpetent
Secondary where immune response occurs
Functions of lymph nodes
Filters lymph looking for pathogens,
Immune system activation proliferation of lymphocytes
What is white pulp and red
White pulp lymphocytes red pulp venous sinuses
Understand the functions of the spleen
Prolife lymphocyte"stores iron' stores platelets' produce rbc in infants,remove damaged and old rbc,easy to damage hard to repair
T cells mature, produce thymmosin and thymopoetin for maturing tcells
Grows till puberty then it decreases in size
Mucosa associated lymphoid tissue aka tonsils how many do we have
Adenoids r known as what?
Which tonsils r most prone to infection
Why r tonsils located there
1st pathogen airborn responce
Where r peyers patches located
Distal small infection
What r peyers patches functions
Able to fight detect food born pathogens-collection of lymphocytes-similar structure in appendix
What is the main goal of the 1st line of defense?
To keep pathogens out
How do the various components of 1st line of defense work?
