BLOOD VESSEL SPASM

PLATLET PLUG CLOTTING

/image.bloodline.net

BLOOD VESSEL SPASM

VASOSPASM: SMOOTH MUSCLE CONTRACTS WHY?

REFLEX A FEW SECONDS, DIRECT STIMULTATION LASTS 30 MIN

PLATELETS RELEASE SEROTONIN WHICH AGMENTS THIS REACTION

PLATELET PLUG

PLATELETS ATTACH TO COLLAGEN EXPOSED UNDER EPITHELIAL LINING

COLLAGEN CAUSES THE PRODUCTION OF MANY TINY SPINOUS PROCESSES ON PLATELETS SO STICK TOGETHER TO FORM A PLUG

ONLY WORKS ON SMALLER BLOOD VESSEL BREAKS

BLOOD COAGULATION/CLOT WOUND = EXTRINSIC FACTORS FOREIGN SURFACE (PLASTIC) =

INTRINSIC FACTORS CASCADE: A SERIES OF REACTIONS

THAT ALL STIMULATE THE NEXT REACTION.

DEPENDS ON AMOUNT OF PROCOAGULANTS AND ANTICOAGULANTS

USUALLY MORE ANTICOAGULANTS

EXTRINSIC CLOTTING MECHANISM

WOUND: RELEASES TISSUE THROMOPLASTIN (FACTOR III)

WHICH EVENTUALLY CONVERTS THROMBOPLASTIN USING CALCIUM AND FORMING PROTHROMBIN ACTIVATOR

PROTHROMBIN ACTIVATOR CHANGES PROTHROMBIN (ALPHA GLOBULIN) TO THROMBIN

THROMBIN CHANGES FIBRINOGEN TO FIBRIN

FIBRIN STICKS TO DAMAGED SURFACES, TRAPS CELLS AND PLATELETS = CLOT

POSITIVE FEEDBACK ??? GENERALLY BLOOD ONLY

COAGULATES WHERE IT IS STILL OR SLOW

BLOOD NORMALLY CARRIES THROMBIN AWAY KEEPING ITS CONCENTRATION TOO LOW FOR COAGULATION AND ANTITHROMBININ BLOOD AND ON VESSEL WALLS KEEPS THROMBIN FROM FORMING

INTRINSIC FACTOR

WHEN EXPOSED TO COLLAGEN OR GLASS IT STIMULATES HAGEMAN FACTOR (FACTOR XII); ACTIVATES FACTOR XI; ACTIVATES FACTOR IX; ALONG WITH FACTOR VIII AND PHOSPHOLIPIDS ACTIVATES FACTOR X

FACTOR X PLUS CALCIUM IONS PRODUCES PROTHROMBIN ACTIVATOR

THEN LIKE EXTRINSIC FACTOR

BLOOD CLOTS FATE DRIES AND SHRINKS PULLING EDGES IN PLATELETS RELEASE PLATELET-DERIVED

GROWTH FACTOR (PDGF) STIMULATE FIBROBLASTS AND SMOOTH MUSCLE TO REPAIR DAMAGE

FIBROBLASTS PRODUCE CONNECTIVE TISSUE FIBERS TO STRENGTHEN CLOT

PLASMINOGEN PICKED UP BY FIBERS PLASMINOGEN ACTIVATOR FROM

LYSOSOMES CAUSES PLASMINOGEN TO BECOME PLASMIN WHICH IS AN ENZYME THAT DIGESTS FIBRIN

THROMBOSSIS: ABNORMALLY FORMED BLOOD CLOT

EMBOLUS: A CLOT THAT BREAKS FREE

EMBOLISM: A BLOCKAGE DUE TO AN EMBOLUS

ATHEROSCLEROSIS: ACCUMULATION OF FATS ALONG BLOOD

VESSEL WALLS ??

PREVENTION OF CLOTS SMOOTH ENDOTHELIUM

ENDOTHELIAL CELLS SECRETE A PROSTAGLANDIN: PROSTACYCLIN

PREVENTS PLATELETS FROM STICKING THROMBIN ABSORBED BY FIBRIN THREADS SO IT

CAN’T SPREAD ANTITHROMBIN: ALPHA GLOBULIN

BINDS THROMBIN AND PREVENTS ACTION ON FIBRINOGEN

HEPARIN FROM: MAST CELLS AND BASOPHILS (ESPECIALLY

LIVER AND LUNGS) ?? INTERFERES WITH PROTHROMBIN ACTIVATOR
