CSMLS Question and answers already passed CSMLS Hemostatic plug formation - correct answer -injury = activator substances -subendothelium exposed -vasoconstriction -platelet adhesion to subendothelium -platelet aggregation = temporary plug -extrinsic=fibrin formation, secondary plt aggregation intrinsic = fibrin formation -platelet retraction = hemostatic plug -fibrinolysis/natural anticoagulants vascular hemostasis - correct answer -muscular: immediate nervous response -hum...

Coagulation Question and answers correctly solved Coagulation - CSMLS What are the requirements of normal blood flow? - correct answer smooth blood vessels allowing blood to escape in the surrounding tissues What is the timeline for vascular injury (after the sub endothelium is exposed) - correct answer 1-2 seconds: vessel constricts, PLTs adhere 10-20 seconds: PLT aggregate 1-3 minutes: PLT plug formed, reinforced with fibrin 3-5 minutes: PLT/fibrin plug contracts 5-10 minutes: ...

ANTICOAGULATION EXAM REVIEW QUESTIONS AND ANSWERS, GRADED A+ Define hemostasis the bloods ability to maintain flow and minimize blood loss at the site of injury by balancing clot formation and anticoagulation systems What are the stages of hemostasis? 1. Vasoconstriction 2. Primary Hemostasis - form a platelet plug 3. Secondary Hemostasis - form a fibrin clot Primary hemostasis formation of a platelet plug 1. Platelet activation 2. Adhesion 3. Secretion 4. Aggregation Describe t...

Processes of platelet activation - ANSWER-Adhesion, activation, aggregation function of platelets - ANSWER-blood clotting Function of Erythrocytes (RBCs) - ANSWER-Transport gases (O2 and CO2) Transport electrolytes Regulate diffusion across cell membrane function of leukocytes (WBC) - ANSWER-defense and immunity Types of Leukocytes (WBCs) - ANSWER-Granulocytes: -Neutrophils -Basophils -Eosinophils Agranulocytes: -Monocytes -Macrophages -Lymphocytes -Natural Killer Cells (NK...
