Coagulation cascade - Study guides, Class notes & Summaries

Coagulation Cascade Exam Containing 40 Questions & Answers/ Already Graded A+ 2024. Terms like; sequence of hemostasis - Answer: 1. Vessel injury provokes vasoconstriction (neural) 2. Endothelin, P-selectin, von Willebrand factor (vWF) are released from Weibel-Palade organelles in endothelial cells 3. Platelets roll on endothelium, adhere to sub-endothelial connective tissue via vWF 4. Leukocytes roll on endothelium, release microparticles, enter vessel wall

The Coagulation Cascade: Extrinsic and Intrinsic Pathways Test Questions Containing 62 terms with Verified Solutions. Terms like; What factors, platelet factors or vascular components activate the extrinsic pathway? - Answer: 1. Factor 3 (Tissue Factor/Thromboplastin) is released from damaged tissue and forms a complex with --> 2. VII and Ca ++ 3. This complex (Tissue Factor + VIIa + Ca++) converts X to Xa --> converts prothrombin to thrombin 4. Thrombin converts fibrinogen to fibrin ...

how does inflammatory process contribute to reperfussion injury? Correct Answer: as oxygen is reintroduced it comes in contact with damaged proteins triggering inflammatory response how does oxidative process contribute to RI? Correct Answer: RAS causes impairment of cell membrane and pro-apotptoic cells release. making cell unstable what is primary Hypertension? Correct Answer: Essential or idiopathic, elevated BP without an identified cause, accounts for 90 - 95% of all cases of hyper...

Coagulative and liquifactive What is coagulative necrosis? necrosis caused y interruption of blood flow l/t desrease Ph, and bacterial growth What causes cell death in MI? unstable plaque breaks off, triggering platelet aggregation, coagulation cascade and thrombus formation. continued no bl...

Purpose of the coagulation pathway - ANSWER-MAINTAIN HEMOSTASIS -inhibits bleeding, hemorrhage -blocks bleeding with clot formation Primary Hemostasis - ANSWER-Aggregation of platelets to form a plug at the damaged site of exposed endothelial cells Secondary Hemostasis - ANSWER-Includes the 2 main coagulation pathways including the intrinsic and extrinsic pathways. These 2 meet up at a point to form the common pathway Common Pathway - ANSWER-FORMS WHEN THE INTRINSIC AND EXTRINSIC PATHWA...
