fluid filling, lymph capillaries called lymphatic fluid or lymph
-
lymphatic capillaries empty into lymphatic vessels similar to veins including valves, body movement and contractions of smooth muscles propels lymph through system
-
straw colored, clear fluid similar to blood plasma
antibodies
-
-
the body can make proteins that bind to antigens, eventually destroying them
collecting ducts
lumbar, intestinal, and intercostal trunk empty into thoracic duct, more than 2/3 of lymphatic systems drains into this trunk
bronchomediastinal, subclavin and jugular trunks empty into lymphatic duct
-
pathology connections
tonsillitis
inflammation of the tonsils, usually caused by bacterial or viral infection
-

Treatment
bacterial
-
In both types symptoms managed with rest, fluids, and analgesics like Tylenol

lymph Organs
spleen
functions to remove and destroy old , damaged, or fragile RBC
-
surrounding blood sinuses are island of white pulp containing lymphocytes and island of red pulp containing both RBC's and WBCs
-
spongy organ in upper left quadrant of abdomen, structurally similar to lymph nodes but instead of lymphatic sinuses has blood sinuses
Thymus
-
gets smaller or even disappears in adults as immune system fully matures in ability to fight infection
-
packed with lymphocytes, which mature unto type of wbc called t-cells
-
lymphatic trunks
trunks, named for the location, include lumbar, intercostal, bronchomediastinal, subclavain, and jugular trunks
