Platelets are some of the most useful parts of your blood!  They hang around in your blood until they are needed and then jump into action.  Platelets are small, have a funny shape and are very sticky.  When you have a cut, they stick together to make a clot (which turns into a scab when it dries) and stops all your blood from leaking out!
