Document Summary
Separation of blood constituents: 3 layers obtained from heparinized blood. Top, yellow: plasma (antibodies with clotting factors) Bottom, red pellet: red blood cells (erythrocytes: non-coated tubes: if you do(cid:374)"t wa(cid:374)t clotting factors. Concentration of cells in human blood: red blood cells, platelets, leukocytes (highest blood concentration to lowest: neverletmonsterseatbabies) Leukocytes (white blood cells: polymorphonuclear/ granulocytes.

Neutrophils: basic or acidic dye (true neutral: mononuclear. Neutrophils: 50-70% of blood leukocytes, multi-lobed nucleus (lobar nucleus) and cytoplasmic granules (primary and secondary granules, large concentration of glycogen in cytoplasm (anaerobic glycolosis) Basophils: 0. 5% of human blood leukocytes, non-phagocytic. Release granule contents: most active in allergic responses. Eosinophils: 1-3% of blood leukocytes, bi-lobed (dumbbell, horseshoe) nucleus with cytosplasmic granules, mature in bone marrow, specialize in tissue (survive 12-14 days in tissue)
