Platelets cling to exposed collagen at the site of injury of a blood vessel. What is the result of this process called?Multiple ChoiceThrombosisPlatelet plugAgglutinationCoagulation

What is initiated by the release of tissue thromboplastin?Multiple ChoiceExtrinsic clotting mechanismIntrinsic clotting mechanismPlatelet plug formationAgglutination

Fill in the Blank QuestionFill in the blank question.Coagulation is the formation of a blood that uses fibrin threads to reinforce a platelet plug.

Hemostasis is the process for stopping bleeding from an injury. Which phase of hemostasis involves collagen fibers being exposed while platelets cling to them.1 pointPhase 1: Vascular SpasmsPhase 2: Platelet plug formationPhase 3: CoagulationPhase 1 and 2

When a blood vessel is injured, what is the first response that takes place?Select one alternative:Exposed collagen fibres promote the adhesion of platelets to the site of injuryVascular spasm - smooth muscle cells of the damaged vessels constrict, reducing the amount of blood flow through the areaPrimary haemostasis: platelets immediately form a "plug" and stop blood lossA blood clot forms

The extrinsic pathway of coagulation is activated by the:Group of answer choicesRelease of tissue factor due to injury.Activation of a proenzyme exposed to collagen.Conversion of prothrombin to thrombin.Sticking of platelets to damaged tissue.
