Blood 2 Flashcards
The ‘BLEEDING’ from many small vessels is known as what?
THROMBOCYTOPENIA PURPURA
*HINT - ‘PURPURA’ = PURPLE
How can ‘THROMBOCYTOPENIA’ be treated?
TRANSFUSIONS OF PACKETED PLATELETS
When the ‘ENDOTHELIAL LINING’ of a vessel is exposed to ‘COLLAGEN PROTEINS’, a process of 3 separate but overlapping mechanisms occurs. What are they?
- VASOCONSTRICTION
- PLATELET PLUG FORMATION
- FORMATION OF BLOOD CLOT
‘VASOCONSTRICTION’ is ‘STIMULATED’ by what during the ‘BLOOD CLOTTING’ process?
SEROTONIN
What causes ‘VASOCONSTRICTION’ during ‘BLOOD CLOTTING’? What are some of the characteristics?
(*There are 3 things)
- VESSEL WALL IS CUT OR BROKEN
- MUSCLES STIMULATED TO CONTRACT
- BLOOD LOSS IS ‘DECREASED’
TRUE OR FALSE
In the absence of ‘VESSEL DAMAGE’, platelets are attracted to each other.
FALSE
‘PLATELETS’ are ‘repelled’ from each other during ‘VESSEL DAMAGE’
What does the ‘PLATELET PLUG’ temporarily do?
TEMPORARILY ‘CLOSES’ THE VESSEL UNTIL CLOTTING MECHANISMS CAN FORM A CLOT.
What is the ‘PLATELET PLUG’ strengthened by?
PROTEIN FIBERS CALLED ‘FIBRIN’
What are the two ‘pathways’ that result in the formation of ‘FIBRIN’?
- INTRINSIC PATHWAY (Inside)
2. EXTRINSIC PATHWAY (Outside)
What is the main difference between ‘EXTRINSIC’ and ‘INTRINSIC’ pathways?
- EXTRINSIC = TISSUE DAMAGE
2. INTRINSIC = VASCULAR DAMAGE
What ‘CLOTTING FACTORS’ does the ‘INTRINSIC PATHWAY’ have that the ‘EXTRINSIC PATHWAY’ does not?
FACTOR 9, 11 AND 12
Where are ‘PROTHROMBIN’ and ‘FIBRINOGEN’ made?
*Hint - They are ‘PLASMA PROTEINS’
MADE IN THE LIVER
What ‘CONVERTS’ ‘PROTHROMBIN’ to ‘THROMBIN’?
CALCIUM
When ‘THROMBIN’ reacts with ‘FIBRINOGEN’ what is the result?
FIBRIN CLOT
What is the ‘COLOR’ of a ‘CLOT’?
NO COLOR
CLOT IS DERIVED FROM ‘PLASMA’ CONSTITUENTS
*THE RED COLOR COMES FROM ‘RBCs’ THAT BECOME TRAPPED.
‘CLOT RETRACTION’ is also referred to as what?
SYNERESIS
‘PLATELETS’ play a role in bringing what closer together?
FIBRIN THREADS CLOSER TOGETHER
Why is ‘CLOT RETRACTION’ important?
DURING ‘INTRAVASCULAR CLOTS’ THE CLOT IS ABLE TO PULL AWAY FROM THE WALL AND ‘RESTORE BLOOD FLOW’
ALLOWS CLOT TO ‘SHRINK IN SIZE’ AFTER TIME
TRUE OR FALSE
CLOTS DO NOT SHRINK IN SIZE
FALSE
‘CLOT RETRACTION’ OR ‘SYNERESIS’ OCCURS BY BRINGING ‘FIBRIN’ THREADS CLOSER TOGETHER.
What is the clotting factor ‘NUMBER’ for ‘FIBRINOGEN’?
I
What is the clotting factor ‘NUMBER’ for ‘PROTHROMBIN’?
II (2)
What is the clotting factor ‘NUMBER’ for ‘TISSUE THROMBOPLASTIN’?
III (3)
What is the clotting factor ‘NUMBER’ for ‘CALCIUM’?
IV (4)
What is the clotting factor ‘NUMBER’ for ‘ANTIHEMOPHILIC GLOBULIN’?
VIII (8)
What is the clotting factor ‘NUMBER’ for ‘CHRISTMAS FACTOR’?
IX (9)
What is the clotting factor ‘NUMBER’ for ‘FIBRIN STABILIZING FACTOR’?
XIII (13)
What is the ‘NAME’ for clotting factor ‘I’?
FIBRINOGEN
What is the ‘NAME’ for clotting factor ‘II’?
PROTHROMBIN
What is the ‘NAME’ for clotting factor ‘III’?
TISSUE THROMBOPLASTIN
What is the ‘NAME’ for clotting factor ‘IV’?
CALCIUM
What is the ‘NAME’ for clotting factor ‘VIII’?
ANTIHEMOPHILIC GLOBULIN
What is the ‘NAME’ for clotting factor ‘IX’?
CHRISTMAS FACTOR
What is the ‘NAME’ for clotting factor ‘XIII’?
FIBRIN STABILIZING FACTOR
What ‘CLOTTING FACTOR’ is the cause of ‘HEMOPHILIA’?
FACTOR VIII (8)
ANTIHEMOPHILIC GLOBULIN
What do ‘ANTICOAGULANTS’ do?
PREVENT ‘BLOOD CLOTTING’
‘ANTICOAGULANTS’ are also referred to as what?
‘BLOOD THINNERS’
What is ‘DICOUMARAL’ (COUMADIN)?
How does it function?
ANTICOAGULANT (BLOOD THINNER)
INTERFERES WITH ‘VITAMIN K’ WHICH ALSO AFFECTS FACTORS VII, IX, AND X.
*LIVER ‘MUST’ HAVE VITAMIN K TO PRODUCE CLOTTING FACTORS
What is ‘HEPARIN’?
How does it function?
INTERFERES WITH THE FORMATION OF ‘THROMBIN’ FROM ‘PROTHROMBIN’
*HEPARIN SHOTS GIVEN TO PATIENTS BEFORE SURGERY TO ‘PREVENT’ CLOTTING DURING/AFTER SURGERY.
How do ‘CITRATES’, ‘OXALATES’ and ‘EDTA’ work as ‘ANTICOAGULANTS?
TIE UP CALCIUM
Where is ‘VITAMIN K’ produced (greatest source)?
Where is it ‘STORED’?
PRODUCED = ‘G.I. TRACT VIA BACTERIA’
STORED = ‘LIVER’
‘NEWBORN BABIES’ do ‘NOT’ have ‘BACTERIA’ in their G.I. tract. Because of this, what usually happens after a baby is delivered?
INJECTED WITH A ‘VITAMIN K’ SHOT
What is the definition of ‘FRIBRINOLYSIS’?
LYSIS OF CLOTS
How does the ‘FIBRINOLYSIS’ begin?
CLOT STIMULATES RELEASE OF A SUBSTANCE FROM THE ‘WALL’ OF A BLOOD VESSEL
There is an ‘ACTIVATOR’ located in the ‘PLASMA’ which stimulates what to occur? With what protein does this start with?
LYSIS OF CLOTS
STARTS WITH ‘PLASMINOGEN’ PROTEIN
When an ‘ACTIVATOR’ is stimulated after a clot is formed, what is the ‘PATHWAY’ for the clot to decompose?
(*There are 4 steps)
‘PLASMINOGEN’ -> ‘PLASMIN’ -> ‘FIBRIN’ -> DEGRADED FIBRIN PRODUCTS
What is the ‘NATURALLY’ ocurrig agent in the body that breaks up clots?
‘PLASMIN’
TRUE OR FALSE
‘PLASMIN’ is very ‘QUICK’ at removing clots in the body.
FALSE
‘PLASMIN’ is natural but ‘NOT’ quick.
What are the 4 conditions that can cause ‘EXCESSIVE’ bleeding in humans?
