Definition
1. neutrophils (60-70%)—phagocytes; polymorphonuclear leukocytes (PMNs), segmented nucleus (segs) poly- morph/o, nucle/o, -ar
2. eosinophils (2-4%) increase in response to allergic reaction; stain “rosy” pink color.
3. Basophils (<1%) Secrete histamine released in allergic reaction. Secrete heparin (anticoagulant) stain dark blue |

Term
Blood clotting--hemostasis
IN ORDER |
|
Definition
1. Injury
2. Platelets “disintegrate”, rupture, break up
3. Thromboplastin Converts prothrombin (blood protein) to thrombin (thromb/o, -in) an active enzyme; requires calcium
4. Thrombin converts fibrinogen (another blood protein) to fibrin (fibr/o, -in); also requires calcium and other clotting factors.
5. Insoluble fibrin threads form mesh that captures cells, creates “plug” for hole.
