What is the role of platelets?

Explanation:
Platelets are responsible for stopping bleeding by initiating clotting (hemostasis). When a blood vessel is damaged, platelets quickly gather at the injury, stick to the exposed area and to each other to form a temporary plug. They release chemicals that kick off the coagulation process, turning fibrinogen into fibrin to create a stable clot that seals the wound and minimizes blood loss. This is different from carrying oxygen (that’s the job of red blood cells), regulating blood sugar (involves hormones and other organs), or defending against infection (the role of white blood cells).
