Final answer:
Coagulation is the process through which fibrinogen is converted into fibrin threads, forming a mesh that helps produce a blood clot. This is crucial for stopping bleeding and starting the healing process.
Step-by-step explanation:
The process where a protein in the blood called fibrinogen is converted into fibrin threads is known as Coagulation. During coagulation, fibrinogen is transformed into fibrin, which forms a mesh that traps platelets and erythrocytes (red blood cells), thereby producing a blood clot. This cascade of events is critical in stopping bleeding by sealing the site of injury and initiating the healing process. The fibrin threads form a network that stabilizes the clot against the vascular wall and provides a framework for the repair of the injured tissue.
