Platelets prevent blood loss and bacterial entry. This describes which function?

Clotting is the process by which platelets help stop blood loss and form a barrier that also helps limit bacterial entry. When a blood vessel is damaged, platelets quickly gather at the site to form a temporary plug and release signals that start the coagulation cascade. This leads to fibrin forming a stable mesh that solidifies the plug into a lasting clot, sealing the wound and reducing infection risk. Leucocytes are white blood cells involved in immune defense, erythrocytes carry oxygen, and arteries are blood vessels; they don’t describe the role of platelets in stopping bleeding.
