Quizplus · Accepted Answer

Platelets have a variety of important functions to:
·react to injury of vessels by forming an aggregate plug or platelet mass that can physically slow down or stop blood loss.
·help activate and be a participant in plasma coagulation to more effectively serve as a barrier to extensive blood loss.
·maintain the endothelial lining of the blood vessels.
 In addition,in the formation of a platelet plug,fibronectin is secreted by endothelial cells and platelets.Platelet Factor 3 (PF3)is a phospholipoprotein (phospholipid)that is contained on or within the plasma membrane of the platelets and is needed in activating certain of the coagulation factors.
