Thrombocytes
Thrombocytes or blood platelets are the smallest cells in the blood. They are seedless cells that play an important role in blood coagulation (haemostasis).
Like erythrocytes, thrombocytes are not cells in the classical sense because they are not capable of division due to a lack of genetic information (DNA). Their task is thrombocyte adhesion (″Thrombozytenanhaftung″), thrombocyte aggregation (″Vereinigung″) for blocking injured blood vessels and the release of numerous coagulation-promoting substances such as coagulation factors and messengers.
