| blood | circulating tissue of the body consisting of fluid with formed elements (red blood cells, white blood cells, and platelets) suspended in the fluid |
| plasma | liquid portion of the blood and lymph; contains water, proteins, and cellular components (i.e., white blood cells, red blood cells, and platelets) |
| serum | liquid portion of the blood that remains after clotting |
| red blood cell (RBC) | transports oxygen and carbon dioxide; also called erythrocyte |
| erythrocyte | transports oxygen and carbon dioxide; also called red blood cell |
| hemoglobin | the protein-iron compound in erythrocytes that transports oxygen and carbon dioxide |
| white blood cell | protects the body from harmful invading substances; also called leukocyte |
| leukocyte | protects the body from harmful invading substances; also called white blood cell |
| granulocytes | a group of leukocytes containing granules in their cytoplasm |
| neutrophil | a granular leukocyte, named for the neutral stain of its granules, that fights infection by swallowing bacteria (phagocytosis) (neutr = neither; phil = attraction for) |
| polymorphonuclear (PMN) leukocyte | another term for neutrophil, referring to the many segments in its nucleus (poly = many; morpho = form; nucleus = kernel) |
| basophil | a granular leukocyte, named for the dark stain of its granules, that brings anticoagulant substances to inflamed tissues (baso = base; phil = attraction for) |
| eosinophil | a granular leukocyte, named for the rose-colored stain of its granules, that increases in allergic and some infectious reactions (eos = dawn-colored [rosy]; phil = attraction for) |
| agranulocytes | a group of leukocytes without granules in their nuclei |
| monocyte | an agranulocytic leukocyte that performs phagocytosis to fight infection (mono = one) |
| lymphocyte | an agranulocytic leukocyte that is active in the process of immunity; the three categories of lymphocytes are T cells (thymus-dependent), B cells (bone marrow-derived), and natural killer (NK) cells |
| platelets | cell fragments in the blood that are essential for blood clotting (coagulation); also called thrombocytes |
