What is the intrinsic path of blood clotting This path is found on the inside of tissue cells. Its trigger is collagen and platelet phospholipids, this causes the formation or activation of clotting factor X. This is a slow process, it takes minutes.
What is the value of having two clotting pathways If one doesn't work you have another.
What is clot retraction and how does it occur When a blood clot becomes smaller and draws the edges of a broken blood vessel together, this involves the shortening of fibrin threads and the squeezing out of excess serum.
What is fibrinolysis and how does it occur It is the dissolving of a clot.
What are plasminogen and plasmin it is the precursor to plasmin found in blood plasma and serum. It is an enzyme that dissolves the fibrin of clots.
