The most abundant - least abundant leukocytes 9 of 34 Neutrophils, eosinophils and basophils are all part of which group Granulocytes 10 of 34 The granules in granulocytes stain specifically with _________ stain Wright's 11 of 34 __________ are the bodies' 'bacteria slayers' - bacterial killing is promoted by the respiratory burst Neutrophils 12 of 34 ___________ are the bodies' defence against parasitic worms Eosinophils 13 of 34 __________ are the rarest leukocytes and their granules contain histamine which contributes to the inflammatory response Basophils 14 of 34 This granulocyte is very similar to mast cells, despite arising from different cell lines Basophils 15 of 34 Lymphocytes and monocytes are _____________ Granulocytes 16 of 34 __________ are the second most abundant leukocyte in the body Lymphocyte 17 of 34 _____________ play a crucial role in immunity by producing T cells an B cells Lymphocytes 18 of 34 __________ are the largest leukocytes Monocytes 19 of 34 When _________ leave the bloodstream they differentiate into highly mobile macrophages which are actively phagocytic Monocytes 20 of 34 After differentiation, these agranulocytes are crucial to the body's defence against viruses, intracellular bacterial parasites and chronic infections Monocytes 21 of 34 The production of white blood cells is known as Leukopoiesis 22 of 34 Leukopoiesis is stimulated by chemical messengers known as haemopoietic factors: interleukins and ___________ Colony stimulating factors 23 of 34 Overproduction of abnormal leukocytes is known as Leukemia and infectious mononucleosis 24 of 34 An abnormally low white blood cell count is known as Leukopenia 25 of 34 Glucocortioids and anti-cancer drugs are common causes of an abnormally low white blood cell count, this condition is known as Leukopenia 26 of 34 Myeloid leukemia affects which cells? Myeloblast and descendants 27 of 34 Lymphocytic leukemia affects which cells? Lymphocytes and descendents 28 of 34 Leukemia is known as _________ if it derives from stem cells Acute 29 of 34 Leukemia is known as ________ if it involves proliferation in the later stages Chronic 30 of 34 Acute leukemia is common in _______ Children 31 of 34 Chronic leukemia is common in ________ Adults 32 of 34 Which condition is commonly known as 'kissing disease'?
