platelets

[plat′lits]

Etymology: Fr, small plate

the smallest cells in the blood. They are formed in the red bone marrow, and some are stored in the spleen. Platelets are disk-shaped, contain no hemoglobin, and are essential for the coagulation of blood and in maintenance of hemostasis. Normally between 200,000 and 300,000 platelets are found in 1 mL³ of blood. Also called thrombocyte. Compare erythrocyte, leukocyte. See also thrombocytopenia, thrombocytosis.
