What helps the blood to seal and clot?

Blood clotting, or hemostasis, is primarily facilitated by platelets and clotting factors. When a blood vessel is injured, platelets quickly adhere to the site and aggregate to form a temporary plug. This process is supported by a series of complex biochemical reactions involving clotting factors, which ultimately lead to the conversion of fibrinogen to fibrin, creating a stable clot that seals the wound. Additionally, substances like calcium ions and vitamin K play essential roles in the clotting cascade.
