What are platelets?
Quick Answer
Platelets are tiny cell fragments that help blood clot after injury. They gather at damaged blood vessels to help stop bleeding.
The Full Story
Platelets, also called thrombocytes, are small fragments made from megakaryocytes in the bone marrow. When a blood vessel is injured, they stick to the damaged area and to each other, forming an initial plug. They also release signals that activate the clotting cascade and help stabilize the wound. Too few platelets can cause bleeding problems, while too many can raise clotting risk.
