What is the function of platelets?

Among the most important components in human blood are platelets – platelets. Their number can change during the day: in the daytime there are more of them than at night. To avoid the risk of fatal diseases, their level must always be maintained within normal limits. The main function of platelets is to protect the integrity of blood vessels. In the event of a wound, platelets cover the injury and stop the blood. Platelet life is short. After 5 – 11 days, their destruction occurs.
