Platelet Activation and Aggregation

Platelet activation and aggregation are essential processes in blood clotting. When a blood vessel is injured, platelets, which are small cell fragments in the blood, become activated. This means they change shape and release chemical signals to attract more platelets. Activated platelets then stick together, or aggregate, forming a temporary plug to seal the injury. This helps stop bleeding and sets the stage for the formation of a stable clot. Overall, this is a crucial response to protect the body from excessive blood loss and support healing.
