Thrombocytes are essential for the coagulation

They are also known as platelets which are found in the blood. Thrombocytes are formed in the bone marrow. For example, when an injury occurs, the bleeding starts

and platelets will disintegrate. They release clotting factor III known as thromboplastin. Thromboplastin in the presence of calcium ions activates prothrombokinase and

leads to a series of reactions causing a blood clot.
