    Study Notes

    Hemostatic Components

    • The three hemostatic components are: blood vessels, platelets, and coagulation factors

    Endothelium Properties

    • Intact endothelium has anticoagulant properties, preventing clot formation and platelet adhesion

    Platelet Characteristics

    • Functional characteristics of platelets include: adhesion, aggregation, and release of granules
    • Platelets are produced in the bone marrow through megakaryocytopoiesis
    • Platelets have a lifespan of 7-10 days and are removed from circulation by the spleen

    Coagulation in Hemostasis

    • Coagulation plays a crucial role in hemostasis by forming a clot to stop bleeding
    • Coagulation involves a complex cascade of reactions involving clotting factors

    Hemostatic Defects

    • Major hemostatic defects are classified under: vascular defects, platelet defects, and coagulation defects

    Platelet Function

    • The main function of platelets in hemostasis is to form a platelet plug to stop bleeding

    Viscous Metamorphosis

    • Viscous metamorphosis is the process by which platelets change shape and become more sticky, allowing them to aggregate and form a platelet plug

    Primary and Secondary Hemostasis

    • Primary hemostasis refers to the formation of a platelet plug, which is temporary and fragile
    • Secondary hemostasis refers to the formation of a stable clot through the deposition of fibrin, which reinforces the platelet plug
    • Primary hemostasis is reversible, while secondary hemostasis is irreversible

    Common Myeloid Progenitor (CMP) Cell

    • A CMP cell gives rise to megakaryocytes, which produce platelets

    Secondary Hemostasis

    • The defining characteristic of secondary hemostasis is the formation of a stable clot through the deposition of fibrin
