Exam1- Blood Clotting: 6 steps

Step 5

Fibrin network traps RBCs and platelets: forming a blood clot

Step 2

Clotting factors convert an inactive blood protein into pro-thrombin activator

Step 1

Injured vessel walls and platelets release clotting factors

Step 3

Prothrombin activator converts prothrombin into thrombin

Step 4

Thrombin converts fibrinogen into fibrin

Step 6

When healed: plasmin (formed from plasminogen) digests the fibrin strands of the clot
