39
Q

how does blood clotting occur?

A

injury> constriction> platelet plug> clot> repair

40
Q

what is the sequence of clotting?

A

extrinsic (damaged cells) & intrinsic (foreign surface)> prothrombin activator changes prothrombin > thrombin, thrombin is changed into fibrinogen> fibrin> mixes with RBC, platelets & plasma> blood clot

41
