Platelets. Platelets are small blood components that help the clotting process by sticking to the lining of blood vessels. Platelets are made in the bone marrow and survive in the circulatory system. Platelets are prepared by using a centrifuge to separate the platelet-rich plasma from the donated unit of whole blood. Platelets may also be obtained from a donor by a process known as apheresis, or plateletpheresis.
