Explanation:
Detailed explanation-1: -Platelets are tiny blood cells that help your body form clots to stop bleeding. If one of your blood vessels gets damaged, it sends out signals to the platelets. The platelets then rush to the site of damage and form a plug (clot) to fix the damage.
Detailed explanation-2: -Injury triggers a reaction in the blood vessel, and activates platelets (specialised blood cell fragments) and clotting factors (specific proteins) in the blood, which work together to slow and stop the bleeding. A clot is formed over the damaged area, which the body will naturally dissolve when the injury has healed.
