Platelets help your blood to clot by forming a temporary plug in the wound that helps stop the bleeding.A wide variety of patients need platelets. Children and adults with cancer use platelets, as well as people undergoing organ transplants, bone marrow transplants, and heart surgery.Platelets are naturally produced by the human body to help prevent blood loss. They work with the protein fibrinogen, vitamin K and the mineral calcium to form clots. Clotting starts once the blood comes in contact with air. Scabs are external blood clots, while bruises are formed internally. A clot that forms inside a healthy vessel can reduce oxygen flow through the blood and lead to a stroke.

Platelets stop bleeding by producing blood clots. Platelets are naturally produced by the human body to help prevent blood loss. They work with the protein fibrinogen, vitamin K and the mineral calcium to form clots. Clotting starts once the blood comes in contact with air.

The process of spreading across the surface of a damaged blood vessel to stop bleeding is called adhesion—when platelets get to the site of the injury, they grow sticky tentacles that help them adhere. They also send out chemical signals to attract more platelets to pile onto the clot in a process called aggregation.
