Basic Concepts Flashcards
Process of cessation/stopping of bleeding
Hemostasis
Hemostasis happens through
Clot formation
Clot dissolution
Clot formation is for
Stopping of bleeding
Clot dissolution is a process of
Removing excessive clot
Substances needed clot formation
Prothrombin
Substances needed for clot dissolution
Antithrombin
Fibrinolytic
Substance that stops or retards chemical reaction
Inhibitors
Condition by which clot obstruct the blood vessel
Thrombus
Condition by which a mass of clot is disseminated in the circulation
Embolus
Process of forming FIBRIN CLOT
Coagulation
Process of breaking down clot
Fibrinolysis
condition by which there is a continuous blood clot formation
DIC
Disseminated Intravascular Coagulation
Treatment for DIC
DIC/Warfarin
Abnormal thickening / hardening of blood vessel wall
Arteriosclerosis
Dislodged calcium, lipids, and cholesterol
Atherosclerosis
2 theories of Hematopoiesis
Monophyletic
Polyphyletic
Widely known theory; all cell came from SINGLE PROGENITOR CELL
Monophyletic
All cell lineages has own stem cell
Polyphyletic
Stem cell in bone marrow produces 2 progenitor cells known as
Myeloid
Lymphoid
Myeloid progenitor cell give rise to what cells
RBC
Platelets
WBC
Lymphoid progenitor cell give rises to
NK cell
T cell
B cell
Precursor cell of platelets are
Megakaryocyte
Process by which platelets are formed from megakaryocyte
Cytoplasmic fragmentation
