Blood and Lymphatic System
Term | Definition |
---|---|
Blood systems | transport O2, nutrients and hormones; carries wastes and CO2 from the cells |
Lymphatic systems | protects the body by clearing foreign bodies; supports immune response; maintains internal fluid environment and carries fat away from digestive organs |
blast/o | germ or bug |
chrom/o & chromat/o | color |
chyl/o | juice |
morph/o | form |
myel/o | bone marrow or spinal cord |
reticul/o | a net |
plasma | liquid portion of blood and nymph; has water, proteins and cellular components |
serum | what remain after clotting |
granulocytes | a group of leukocytes that have granules in their cytoplasm; neutrophils, basophils and eosinophils |
neutrophils/ polymorphonuclear leukocyte | granular; fight infection by swallowing bacteria |
basophil | named for dark stain on granules; brings anticoagulant substances to inflamed tissues; elevates allergic reactions |
eosinophils | rose colored granules; fight substances related to parasitic infection that have been flagged for destruction by your immune system. Regulating inflammation |
monocyte | agranulocyte; performs phagocytosis |
lymphocyte | active in the process of immunity; B cells, T cells and natural killer cells |
thymus | primary gland of the lymphatic system; superior to the heart; produces T lymphocytes |
spleen | filters out aging blood cells, cell debris and provides an environment for immune activation |
lacteals | specialized vessels in the small intestine that absorbs fat into the bloodtsream |
chyle | white or pale yellow substance in lymph that contains fatty substances absorbed by the lacteals |
lymph ducts | carries lymph from lymph nodes to veins; right lymphatic and thoracic |
active immunity | long-lasting immunity that results from stimulating the body to produce its own antibodies; naturally vs. artificially |
passive immunity | short term immunity; naturally placenta to fetus or artificially by injecting serum containing antibodies |
microcytosis | presence of small red blood cells |
macrocytosis | big red blood cells |
anisocytosis | presence of red blood cells of unequal size |
poikilocytosis | presence of large, irregularly shaped RBCs |
reticulocytosis | immature erythrocytes in the blood |
erythropenia | reduced number of RBCs |
lymphcytopenia | reduced number of lymphocytes |
neutropenia | decreased number of neutrophils |
pancytopenia | reduced number of cellular components in the blood |
thrombocytopenia | decreased number of platelets in the blood |
lymphadenopathy | enlarged (disease) lymph nodes |
splenomegaly | big spleen |
AIDS | caused by HIV; renders immune cells ineffective |
anemia | diminished ability to carry oxygen |
aplastic anemia | failure of bone marrow to produce RBCs |
iron deficiency anemia | lack of iron in blood; affects production of hemoglobin |
pernicious anemia | inadequate supply of B12, causing RBCs become large, varied in shape and reduced in number |
erythroblastosis fetalis | a disorder that results from the incompatibility of a fetus with Rh-positive blood and a mother with Rh-negative blood, causing RBC destruction in the fetus. Requires blood transfusion |
Rh factor | antigen on surface of RBCs; derived from Rhesus monkey |
hemochromatosis | excessive build up of iron deposits in the body |
leukemia | cancerous disease of blood forming organs, abnormal leukocytes in blood and bone marrow |
myelodysplasia | disorder w/i bone marrow characterized by proliferation of abnormal stem cells |
lymphoma | neoplastic disorder of lymph tissue; usually malignant |
polycythemia | increased number of RBCs and Hgb |
phlebotomy/venomtomy | incision into or puncture of a vein to withdraw blood for testing |
BMP | tests for Ca, CO2, Cl, creatinine, glucose, K+, Na+, and blood urea nitrogen |
CMP | in addition to BMP, tests for albumin, bilirubin, alkaline phosphatase, protein, alanine aminotransferase and aspartate aminotransferase |
CD4 cell count | used to monitor course of HIV; normal range is 600-1500 in a given volume of blood |
partial thromboplastin time | test to determine coagulation defects |
prothrombin time | test to measure activity of prothrombin in the blood |
hematocrit | percentage of packed RBCs in a given volume of blood |
