Substances in plasma, called Factor I, Factor II, and so on, which act one after the other to make the blood coagulate when a blood vessel is damaged.
Commonly referred to as coagulation factors, these are proteins present in the plasma that play a crucial role in initiating different stages of the blood clotting mechanism by transitioning from an inactive to an active state.
In the intricate process of blood clotting, there exists a circulating protein that becomes active. This protein plays a crucial role in initiating a sequence of chemical reactions, which involves various clotting factors. These factors work together in a complex manner, ultimately leading to the formation of a solid mass called a blood clot.
