beneath the left side of diaphragm and in back of the upper part of the stomach

produces leukocytes and antibodies, destroys old blood cells stores erthycoytes to release into bloodstream if excessive bleeding occurs destroys thrombocytes and filters metabolites and wasres from the body

is the thymus replaced by fat and connective tissue after puberty
produces antibodies and manufacture lymphocytes
What does the thymus do in early life?
lymph nodes
what takes over for the thymus?
inflamation or infection of the lymph nodes(occurs when large quanties of pathogens or cancer cells enter the lymph nodes and infect the tissue
antibiotics warm moist compresses or an incise to drain the node
What is the treatment for adenitis?
hodgkin's diseae
chronic malignant disease of the lymph nodes ( symptoms swelling of lymph nodes fever night sweats weight loss fatigue and pruritus (itching)
Chemotherapy and radiation
Treatments for hodgkin's disease
hodgkin's disease is usually curable
inflamation of lymphatic vessels usually resulting from an infection in an extremity
red streak extending up arm or leg from source of infection fever chills pain
symptoms of lymphangitis (treatment antibiotics rest elevation of infected part warm compressess
enlargement of the spleen results from an abnormal accumulation of red blood cells mononucleosis and cirrhosis of the liver
splenomegaly can lead to death if the spleen would rupture
symptoms of splenomegaly are swelling abdominal pain destruction of red blood cells can lead to anemia
spleen can be surgically removed
inflamation infection of the tonsils usually involves the pharyngeal (adenoid) and palatine tonsils
treatment for tonsilitis antibiotics throat irrigations rest and pain medicine chronic or enlargement may indicate need for surglcal removal
