Platelets are the blood component that helps create a scab after cutting your finger. When you cut your finger, platelets immediately gather at the site of the injury to form a plug that helps control bleeding. The platelets release clotting factors, which initiate a complex cascade of reactions leading to the formation of a fibrin clot. This clot serves as a temporary barrier, allowing the wound to heal by preventing further bleeding and providing a scaffold for new tissue formation.
