Which blood component is primarily involved in clotting?

When a blood vessel is damaged, platelets respond first to form the initial clot. They rapidly adhere to exposed vessel walls, change shape, and release chemical signals that recruit more platelets, creating a temporary platelet plug. Platelets also provide surfaces that concentrate clotting factors, helping convert fibrinogen into fibrin to form a stable, lasting clot. Plasma contains the clotting factors used in the cascade, but the actual formation of the clot is driven by these platelet actions. Erythrocytes and leukocytes don’t drive clot formation, though they may be present in a clot.
