Lymphatic System
Diseases :
Tonsillitis
inflammation of tonsils
Cancer Stages
stage one
no spreading
stage 2
spreading to tissues
Stage 3
spreading to lymph nodes
Stage 4
Spreading to organs; terminal
Leukemia
cancer of bone marrow
myelogenous
cells that divide out of control are blood stem cells
lymphocytic
cells that divide out of control are lymphocytes
Inflammation
inflammatory response
Fever
attempt to destroy pathogens by baking them out
RA
attacks synovial membranes
Lupus
Attacks all tissues
HIV/AIDS
immune disorder caused by HIV
Cells
cytokines
proteins produced by damaged tissues
interleukins
involved in every aspect of innate and adaptive immunity
interferon
produced by cells that have been infected by a virus
tumor necrosis factor
produced by WBC's that stimulate macrophages
Complement Cascade
complex series of reactions that activate proteins
Helper T cells
help other lymphocytes
Bcells
responsible for antibody mediated immunity
Immune System
provides weapons and troops to protect from invasion
Antigens
cells have molecules on outer surface of cell
Antibodies
proteins that bind to antigen destroying them
Innate
inborn ability to fight infection
Adaptive
remembers invaders from before
Barriers
anything that prevents infections
Lymphatic Organs
spleen

Lymph capillaries
smallest pipes
Lymph Vessels
capillaries empty into
Lymph Nodes
small encapsulated divided into sections
Trunks
lumbar
intercostal
intestinal
subclavian
jugular trunks
bronchomediastial
Ducts
Thoracic Duct
Lumbar
intestinal
intercostal
Lymphatic Duct
bronchomediastinal
subclavian
jugular
works close with cardiovascular system
functions
recycle fluids lost in CV system
transport pathogens to lymph nodes
storage and maturation of WBC
absorption of glycerol and fatty acids
