Platelets, also known as thrombocytes, are small colorless blood cells that play a crucial role in the process of blood clotting (hemostasis). When there's an injury or damage to a blood vessel, platelets gather at the site to form a plug that helps prevent excessive bleeding. They adhere to the damaged area, release chemical signals to attract more platelets, and begin to form a temporary seal.
In addition to their role in clotting, platelets also contain growth factors and other substances that aid in tissue repair and healing. They contribute to wound healing and tissue regeneration by releasing these factors.
Overall, platelets are essential components of the blood that help maintain the body's hemostatic balance and support the healing process.
