A blood platelet.
A blood vessel that carries deoxygenated blood from the tissues to the heart.
A small vein connecting a capillary to a vein.
White blood cell (WBC)
Blood cell that functions in immunity; leukocyte.
A stable compound formed when azide combines with hemoglobin.
A stable colored compound formed when hemoglobin is reacted with Drabkin's reagent; hemiglobincyanide (HICN)
A hemoglobin diluting reagent that contains iron, potassium, cyanide, and sodium bicarbonate
The protein portion of the hemoglobin molecule
The iron-containing portion of the hemoglobin molecule
A light colored layer of white blood cells and platelets that forms on top of the red blood cell layer when a sample of blood is centrifuged or allowed to stand undisturbed.
A slender glass or plastic tube used in laboratory procedures
The volume of red blood cells packed by centrifugation in a given volume of blood and expressed as a percentage; packed cell volume (PCV)
A hematocrit performed in capillary tubes using a small quantity of blood; packed cell volume (PCV)
An instrument that spins capillary tubes at a high speed to rapidly separate cellular components of the blood from the liquid portion of blood
Packed Cell Column
The layers of blood cells that form when a tube of whole blood is centrifuged
Cell diluting fluid
A solution used to dilute blood for cell counts
A heavy glass slide made to precise specifications and used to count cells microscopically; a counting chamber
A special coverglass of uniform thickness used with a hemacytometer
A pipet that measures or holds 1mL or less
A condition in which the red blood cell count or blood hemoglobin level is below normal; a condition resulting in decreased oxygen-carrying capacity of the blood
An excess of red blood cells in the peripheral blood; sometimes called polycythemia
The rupture or destruction of red blood cells, resulting in the release of hemoglobin
Resistance to disease or infection
A solution with the same concentration of dissolved particles as the solution or cell with which it is compared
A cancer of white blood cells characterized by an abnormal increase of white blood cells and their precursors in bone marrow, tissue, and peripheral blood
Increase above normal in the number of leukocytes (white blood cells) in the blood
Decrease below normal in the number of leukocytes (white blood cells) in the blood; Leukocytopenia
A blood disorder characterized by purpura in skin and mucous

Nucleus (pl. nuclei)
The central structure of a cell that contains DNA and controls cell growth and function
Having many colors
