Hemostasis is the process by which the body stops bleeding in response to injury. It involves a complex series of events, including vasoconstriction, platelet activation and aggregation, and coagulation cascade activation, to form a stable blood clot and prevent excessive blood loss. Dysfunction in the hemostatic process can lead to bleeding disorders or thrombotic events. Research in the field of hemostasis aims to understand the mechanisms underlying normal and pathological hemostasis, as well as to develop new diagnostic tools and treatments for hemostatic disorders.
