It is in the blood and is a clotting factor for when a blood vessel is damaged, those are what came and fill up the hole so you do not bleed to death from a paper cut. Hemophiliacs are defective in platelets and that is why they need blood transfusions and such when they get a cut, for both blood loss and because it gives them platelets so they can form a scab.
