Question

List the sequence of event that occur during the formation of blood clot after an injury

Answer 1

Step 1 - when blood vessels gets injured due to cuts, the blood vessels come in contact with the environment and burst and liberate thromboplAstin which helps in formation of an enzyme prothrombinase. this enzyme inactivates heparin and converts inactive plasma protein, prothrombinase into its active form, thrombin
step 2 -thrombin acts as a proteolytic enzyme and converts soluble fibrinogen molecules into insoluble fibrin monomers
step 3 -fibrin monomers polymerize to form long threads. this threads form a fine network over wound and trap blood corpuscles to form clot
