What is the primary function of platelets?

The primary function of platelets, also known as thrombocytes, is to play a crucial role in blood clotting or coagulation. When a blood vessel is injured, platelets adhere to the site of injury and aggregate to form a plug, preventing further bleeding. They release various substances, such as clotting factors and chemicals, which initiate the clotting cascade, leading to the formation of a stable blood clot. This process helps to stop bleeding and promotes wound healing.
