Option 2, Blood platelets, helps in the circulation of blood. Blood platelets, also known as thrombocytes, are small cell fragments present in our blood. They play a crucial role in the clotting of blood, preventing excessive bleeding when a blood vessel is damaged. When there is a cut or injury, blood platelets are activated and form a clot to seal the wound. This clot helps to stop bleeding and promotes the healing process. Additionally, blood platelets also release certain chemicals which help in the constriction of blood vessels, reducing blood loss further. Therefore, blood platelets are essential for maintaining proper circulation by preventing excessive bleeding and helping in wound healing.
