major functions of the lympathic and immune sytem
pathways - Lymphtic capillary , afferent lymphatic vessel , lymph nod , efferent lymphatic vessedl , lypahtic trunk , collecting dict , subclavin vein
Lymphatic Capillaries- tiny vessels that collect and filter fluid from your body's cells and tissues.
tonsils
thymus
peyer's patches
none marrow
appendix
lymphatic vessles
lymph nodes
Location of Lymphatic organs and their functions
lymph noes -loctaed in groups or chains along lymphatic vessles ,d , afferent lymphatic vessels enter on the convex surface not found in the central nervous system
thymus location - lung , diaphragm , liver , spleen , stomach , heart trachea , thyroid gland
spleen -lies in te ipper let abdominal cavity , largest lynohatic organ in body
purpose and exmples of First , Second , and third line of defense
First line of defense - Mechanical barriers (skin and mucous membrane )
Second line of defense - chemical barriers
- natural killer cells
- inflammation
phagocytosis - fever
Third line of defenae - cellular immune response , - humora immune response
humoral response snd celluar respone
antigens and antibodies
included in adaptive
antibodies trval through the body fluids to attack and destroy antigens ; called humoral immune response
cellualr umminue response or cell mediated immuity - response through cell to cell contact as ativated t cells interact directly with ntigen bearing cells
5 major types
IgG
IgA
IgM
IgE
IgD
Antigens and antibodies
T cells - produce antiboides against the dusplayed antigen
t cells - monitor the bodys cells
b cells - become activated and produce a clone of cells

Disorders associated with the Immune system
Type 1 diabetes. The immune system attacks the cells in the pancreas that make insulin
Rheumatoid arthritis. This type of arthritis causes swelling and deformities of the joints
