Platelets play a key role in the blood clotting process by releasing thromboplastin, which initiates a series of reactions that ultimately results in the formation of a blood clot. They are not specialized red blood cells, do not carry the blood type protein, do not transport carbon dioxide, and are not responsible for the buildup of plaques on artery walls.
