Final answer:
The sequence of chemicals involved in clot formation is Fibrinogen -> Thrombin -> Fibrin. Thrombin converts fibrinogen into insoluble fibrin protein strands, which form a mesh that traps platelets and red blood cells to produce a clot. Factor XIII stabilizes the clot.
Step-by-step explanation:
The sequence of chemicals that are involved in the process of clot formation is: Fibrinogen → Thrombin → Fibrin.
During coagulation, fibrinogen, which is a soluble protein, is converted into insoluble fibrin protein strands by the enzyme thrombin. This conversion is essential for the formation of a clot, as the fibrin strands create a mesh that traps platelets and red blood cells.
Factor XIII then stabilizes the fibrin clot. Once the clot is formed, contractile proteins within the platelets contract, bringing the edges of the clot tightly together and squeezing out serum, which is plasma without its clotting factors.
