1. Thrombocytes are also known as Platelets and are found in blood.

2. They are formed in the bone marrow.

3. When an injury occurs, bleeding starts taking place.

4. This causes platelets to disintegrate and start releasing Clotting Factor III, also known as Thromboplastin.

5. Thromboplastin in the presence of calcium ions activate Prothrombokinase. Which further leads to a series of reactions causing blood clot.
