    Study Notes

    Haemostasis

    • Haemostasis is the process of stopping bleeding or blood loss from a damaged blood vessel
    • It involves three main stages: vasoconstriction, platelet plug formation, and coagulation
    • Vasoconstriction is the constriction of blood vessels to reduce blood flow to the damaged area
    • Platelet plug formation involves the aggregation of platelets to form a temporary plug to seal the damaged vessel
    • Coagulation is the process of forming a blood clot, which is a solidification of blood, to permanently seal the vessel
