Learn about the process of hemostasis and coagulation in the field of hematology, which involves the interaction of vasoconstriction, platelet adhesion, aggregation, and coagulation enzyme activation to stop bleeding. Explore the normal processes involved in hemostasis, including blood vessel spasm, formation of a platelet plug, and coagulation.
