Factors of type I, II, III

Factors of type I, II, and III refer to groups of proteins involved in blood clotting. Type I factors, like fibrinogen, are the building blocks that form the structural mesh of a clot. Type II factors are enzymes, such as thrombin and factor X, that accelerate the clotting process by activating other factors. Type III factors, like tissue factor, initiate the clotting cascade when blood vessels are injured. Together, these factors work in a coordinated sequence to rapidly form a stable blood clot, preventing excessive bleeding while maintaining balance to avoid unnecessary clots.
