Blood Coagulation Cascade

The blood coagulation cascade is a complex process that helps stop bleeding when injuries occur. It involves a series of proteins in the blood that activate each other in a sequential manner. When a blood vessel is damaged, these proteins work together to form a clot by transforming a protein called fibrinogen into fibrin, which creates a mesh that traps blood cells. This mesh hardens to seal the wound, allowing the body to heal. The cascade is crucial for preventing excessive blood loss and is carefully regulated to ensure clots form only when needed.
