Platelets

Platelets are key components of blood which are responsible for clotting and healing of wounds. They are small, disk-shaped cells which lack a nucleus and form part of the body's immune system. Platelets are integral in the prevention of excessive blood loss from wounds by initiating the formation of a blood clot. They also activate other body cells to initiate the repair of the damaged tissue. Platelets play an important role in helping to reduce the risk of stroke and other cardiovascular problems. Additionally, they can be used in the medical setting for therapeutic purposes such as platelet-rich plasma therapy.
