| lymph/o | clear fluid |
| morph/o | form |
| reticul/o | a net |
| splen/o | spleen |
| chromatism | a condition of abnormal pigmentation |
| serum | liquid portion of the blood that remains after clotting |
| erythrocyte | transports oxygen and carbon dioxide |
| hemoglobin | the protein-iron compound in erythrocytes that transports oxygen and carbon dioxide |
| leukocyte | protects the body from harmful invading substances |
| granulocytes | a group of leukocytes containing granules in their cytoplasm |
| basophil | a granular leukocyte, named for the dark stain of its granules, that brings anticoagulant substances to inflamed tissues |
| agranulocytes | a group of leukocytes without granules in their nuclei |
| aplastic anemia | a normocytic-normochromic type of anemia characterized by the failure of bone marrow to produce red blood cells |
| iron deficiency anemia | a microcytic-hypochromic type of anemia characterized by a lack of iron that affects the production of hemoglobin and is characterized by small red blood cells containing low amounts of hemoglobin |
| hemochromatosis | hereditary disorder with an excessive buildup of iron deposits in the body |
| platelets | cell fragments in the blood that are essential for blood clotting (coagulation), also called thrombocytes |
| chyle | white or pale yellow substance in lymph that contains fatty substances absorbed by the lacteals |
| lymph ducts | collecting channels that carry lymph from the lymph nodes to the veins |
| right lymphatic duct | receives lymph from the right upper part of the body |
| immunity | process of disease protection induced by exposure to an antigen |
| antigen | a substance that, when introduced into the body, causes the formation of antibodies against it |
| microcytosis | presence of small red blood cells |
| hypochromic | pale in color; lighter in color than normal |
| lymphoma | any neoplastic disorder of lymph tissue, usually malignant, as in Hodgkin disease |

| lymphangiogram | an x-ray image of a lymph node or lymph vessel obtained after injection of a contrast dye |
| computed tomography (CT) | full body x-ray CT images are used to detect tumors and cancers such as lymphoma |
| lymphadenectomy | removal of a lymph node |
| lymphadenotomy | incision into a lymph node |
| erythropenia | an abnormally reduced number of red blood cells |
| neutropenia | a decreased number of neutrophils |
| hemolysis | breakdown of the red blood cell membrane |
| immunocompromised | impaired immunologic defenses caused by an immunodeficiency disorder or by therapy with immunosuppressive agents |
| immunosuppression | impaired ability to provide an immune response |
