Blood & Lymphatic System - Q – Anatomic Terms in the Blood system & A – Meaning
Question | Answer |
---|---|
plasma | liquid portion of the blood and lymph; contains water, proteins, and cellular components (i.e., leukocytes, erythrocytes, and platelets) |
serum | liquid portion of the blood that remains after clotting |
erythrocyte | red blood cell; transports oxygen and carbon dioxide |
hemoglobin | the protein-iron compound in erythrocytes that transports oxygen and carbon dioxide |
leukocyte | white blood cell; protects the body from harmful invading substances |
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) |
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) |
basophil | a granular leukocyte, named for the dark stain of its granules, that brings anticoagulant substances to inflamed tissues (baso = base; phil = attraction for) |
agranulocytes | a group of leukocytes without granules in their nuclei |
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 |
monocyte | an agranulocytic leukocyte that performs phagocytosis to fight infection (mono = one) |
platelets | thrombocytes; cell fragments in the blood that are essential for blood clotting (coagulation) |
