Which answer choice specifies the correct order of the activities governed by the blood clotting regulatorycascade?1. Platelets expose anionic phospholipids and release thromboxanes.2. Fibrin cross-links and stabilizes collected platelets.3. Tissue damage exposes collagen to the blood.4. Thromboxanes stimulate platelet activation.5. Collagen activates platelets.6. Thrombin cleaves fibrinogen to form fibrin.3, 5, 4, 1, 6, 23, 5, 1, 4, 2, 63, 1, 5, 4, 6, 22, 6, 4, 1, 5, 33, 5, 1, 4, 6, 2

Platelets have all of the following functions except:- a. coagulation. b. plugging broken blood vessels. c. stimulating vasoconstriction. d. transporting oxygen. e. recruiting neutrophils
Select the incorrect statement about hemostasis: O A. In the process of coagulation, the intrinsic and extrinsic pathways lead to the activation of plasmin, which serves to activate fibrinogen, producing fibrin fibrils. O B. In platelet plug formation, platelets begin sticking to the collagen exposed when the vessel wall was damaged. The platelets forming the plug attract more platelets to the area in a positive feedback loop. OC. Coagulation is the process of platelet plug stabilization through the formation of fibrin fibrils. O D. Vascular spasm is the initial phase of hemostasis It begins when a blood vessel is severed, resulting in a reflexive narrowing of the vessel through smooth muscle contraction.
Which protein forms a bridge between exposed vessel wall collagen and platelet surface receptors? Select one: a. von Willebrand factor b. Thromboxanes c. Endothelin d. Fibrinogen
Which of the following statements are true of chemical blood clotting? (Read carefully and select all of the correct statements.) A. Fibrinogen is changed to fibrin in stage 1 of clotting. OB. Stage 1 is the prothrombin activator is formed. OC. Calcium ions are needed for all three stages of clotting. D. The endothelium of blood vessels is smooth and helps prevent abnormal clotting. E. Many of the clotting factors are produced by the liver, but some are produced by the spleen. F. The actual clot is made of fibrin. 100000000 G. The purpose of fibrinolysis is to strengthen a newly formed clot. H. Prothrombin activator changes thrombin to prothrombin. DAMARI Type here to search Ei O E $
