Chapter 5: Lymphatic System Flashcards
lymphatic system consists of
lymph nodes, vessels, fluid; tonsils, thymus, spleen
lymphatic system depends on
pumping of the heart to circulate substances throughout the body
main functions of lymphatic system
drain interstitial fluid from tissues, absorb and transport fat to venous circulation, produce lymphocytes and immune cells
lymph nodes
small masses of lymph tissue in clusters or chains
major groups of lymph nodes
cervical, axillary (armpit) and inguinal
spleen
large lymph node that filters lymph; creates lymphocytes and monocytes, destroys old RBCs, stores new RBCs (not essential to life though)
thymus
secretes thymosin
thymosin
stimulates red bone marrow to produce T cells
tonsils
filter lymph, destroy bacteria entering mouth and throat
tonsill/o

lymphaden/o
lymph gland
aden/o
gland
lymph/o

phag/o
swallowing, eating
-phylaxis
protection
-poiesis
formation, production
lymphedema
accumulation of lymph in extremities - weakness, fatigue, fever, weight loss
treatment of lymphedema
move lymph out of limb with exercise, massage, bandaging, compression sleeve; maybe surgery
systemic lupus erythematosus (SLE)
chronic inflammatory autoimmune disease - unusual antobodies in blood that targets body tissues - butterfly rash on face
SLE produces inflammation commonly
skin, joints, nervous system, kidneys, lungs
treatment of lupus
anti-inflammatory drugs, corticosteroids, mabye anti-malarials, immunosuppresives
kaposi sarcoma
lymphatic malignancy composed of red or purple macules, papules, or nodules
kaposi sarcoma closely related with
HIV/AIDS
treatment of kaposi sarcoma
radiation, chemotherapy, surgery, immunotherapy
hodgkin disease
malignant disease - painless progressive enlargment of lymphoid tissue, splenomegaly, and Reed-Sternberg cells in lymph nodes
lymphadenitis
inflammation and enlargment of lymph nodes; result of infection
lymphocyte
type of white blood cell (leukocyte) responsible for immune response
mononucleosis
acute infection caused by Epstein-Barr Virus - sore throat, fever, fatigue, enlarged lymph nodes
pathogen
any disease-producing microorganism
phagocyte
cells that protect body by ingesting harmful foreign substances
bone marrow aspiration
withdrawn from pelvic bone for microscopic evaluation; used for stem cell transplant, chromosomal analysis, determine spread of cancer
ELISA
blood test that detects antibodies in blood; screening for antibody to AIDS virus
tissue typing
used to determine histocompatability of tissues - used in grafts and transplants with recipients tissues and cells
bone marrow transplant
infusion of healthy bone marrow stem cells after disease bone marrow is destroyed by chemotherapy or radiation
lymphangiectomy
excision of one or more lymph vessels
antivirals
inhibit development of specific viruses
immunosuppressants
suppress immune response to prevent organ rejection after transplantation, slow progression of autoimmune disease
