Flashcard Description: Coagulation is a vital process in the body’s defense mechanism against bleeding. It refers to the formation of a blood clot, which helps to seal off damaged blood vessels and prevent excessive blood loss. Coagulation involves a complex cascade of reactions, where various proteins and platelets interact to form a stable clot. Understanding coagulation is crucial in diagnosing and managing bleeding disorders, as well as in surgical procedures and the development of anticoagulant medications.
