Detailed explanation-1: -The main job of platelets, or thrombocytes, is blood clotting. Platelets are much smaller in size than the other blood cells. They group together to form clumps, or a plug, in the hole of a vessel to stop bleeding.
Detailed explanation-2: -Platelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury. Typically, your body will naturally dissolve the blood clot after the injury has healed.
Detailed explanation-3: -What do platelets do? Your platelets function to stop bleeding. During an injury, your platelets will cluster together at the site of the wound to act as a plug, sealing blood vessels in a process called clotting to prevent excess blood from leaving your body.
Detailed explanation-4: -Blood clotting factors Thrombin converts fibrinogen, a blood clotting factor that is normally dissolved in blood, into long strands of fibrin that radiate from the clumped platelets and form a net that entraps more platelets and blood cells.
