Band Cell Combination of eosin and methylene blue dyes in methanol is Wrights Stain Smears that are _____________ can be caused by the stain time being too short, wash time being too long, or the pH of the stain being too acidic. Too Pink Smears that are _________________ can be caused by over staining, wash time being too short, or pH of the stain being too alkaline. Too Blue The largest circulating WBC Monocyte Smallest WBC Lymphocyte Reduced colour or hemoglobin content is Hypochromic A significant variation on the shape of an RBC is Poikilocytosis A hemoglobin diluting reagent that contains iron, potassium, cyanide, and sodium bicarbonate. Drabkins Reagent What is the area counted in mm squared for a RBC count 0.2 What is the area counted in mm squared for a WBC leuko tic method 4.0 What is the area counted in mmm squared for platlets 1.0 Abnormally high number of platelets in the blood is Thrombocytosis The protein portion of the haemoglobin molecule is Globin The iron containing portion of the haemoglobin molecule is Heme What is the primary component of RBC and is the oxygen carrying molecule Hemoglobin Haemoglobin binds ___________ and transports it to the _______________ and tissues Oxygen, lungs The haemoglobin determination can be performed using either _________________ or ____________________ blood Capillary, venous Hemoglobin makes up over ____________ of red blood cell content 98% A small branch of an artery leading to a Capillery is Arteriole A blood vessel that carries oxygenated blood from the heart to the tissues is Artery A mini blood vessel that connects the smallest arteries to the smallest veins and serves as an oxygen exchange vessel is Capillary The form of haemoglobin that binds and transports oxygen is Oxyhemoglobin A small vein connecting a Capillary to a vein is Venule A blood vessel that carries deoxygenated blood from the tissues to the heart is Vein What is a thrombocyte A blood platelet What is a leucocyte? white blood cell The process of stopping bleeding which includes clot formation and clot in dissolution is Haemostasis The process of blood cell formation and development is Hemopoiesis Arterial blood is bright red because of Oxyhemoglobin Venous blood is dark red because of the presence of Deoxyhemoglobin List the five types of wbc that are present in normal blood Neutrophils, basophils fills, eosinophils, lymphocytes, monocytes neutrophils, eosinophils, basophils, are called ____________ because of granules found in the cell cytoplasm. Granulocytes The shape of a leukocyte is Nuclear shape varies Shape of an erythrocyte is biconcave disc The shape of a thrombocyte is Varied What percentage of the plasma is water 90% An immature erythrocyte that still contains RNA remnants in the cytoplasm is Reticulocyte The nucleic acid that is important in protein synthesis and that is found in all living cells is RNA A nontoxic die used to stay in living cells or tissues is Supra-vital stain The production of red blood cells is erythropoiesis When reticulate stain is applied to recently collected blood the RNA in immature RBC stains as granular aggregate or filaments called a Reticulum The manual reticulocyte count is performed by a microscopic examination of smears of freshly collected blood stained with Methylene blue stain Reticulate procedure can be performed on ______________ or _________________ blood Capillary, Venous EDTA Reticulate procedures should be performed within _____________ hours of blood collection 4 Dry smears are examined microscopically using which objective Oil immersion Newborn infants have high reticulocyte count that decreases to adult levels by__________ weeks of age 2 An increased number of reticulocytes is called Reticulocytosis A decrease in reticulocytes is called Reticulocytopenia Proteins that increase rapidly in plasma during acute infection and inflammation or following tissue injury are Acute Phase Proteins The total substances making up a mass, A cluster of clump of particles is Aggregate
