The plug is composed of platelets and special plasma proteins called fibrin. The platelets pug is enmeshed in a network of insoluble fibrin molecules.
The aggregation of platelets and formation of fibrin both require the enzyme called thrombin. The clotting process also requires calcium ions, and about a dozen other protein clotting factors found in plasma.
When blood vessels are cut or damaged, the loss of blood has to be stopped before shock and possible death occur. This is achieved by solidification of blood, a process called coagulation or clotting.

Answer:
Carbon monoxide has much more affinity for the hemoglobin than the affinity of the oxygen to the hemoglobin almost 300 times more, which allows the Hb to bind with carbon monoxide irreversibly. Due to this, the small quantity of CO can also reduce the ability of oxygen transport of the hemoglobin.
Longer exposure of CO to the cHb will lead to reducing oxygen release by the Hb that is bound to oxygen in this T state which causes less oxygen availability. In aerobic oxidation mechanisms like oxidative phosphorylation will eventually stop. It will be shifted to anaerobic cellular respiration. The net production of ATP drastically reduced due to anaerobic glycolysis. Cells will eventually start to die causing the death of an organism.
