BODY FLUIDS EXAM 3 WITH 100%
CORRECT ANSWERS 2025
Coagulation or _____________ is the process of forming a barrier to
blood loss and limiting it to the injured site.
--Keep blood within the veins & arteries.
--Prevent blood loss from injuries by formation of thrombi.
--Reestablishes blood flow during the healing process. correct
answers >> hemostasis.
Coagulation is often thought of as clot formation, but it also
includes ________________. correct answers >> clot dissolution
and vessel repair.
Hemostasis is achieved by the integrated and regulated
interaction of _____________. correct answers >> Blood
vessels
Platelets
Coagulation Factors
Fibrinolysis
In ______________, vessels constrict to minimize the flow of blood
to the wounded area (after blood vessel injury). Platelets start to
accumulate at the site of injury and form a platelet plug. This plug
temporarily stops the bleeding but is fragile. correct answers
>> primary hemostasis.
,List the 3 stages of normal coagulation. correct answers >>
1. primary hemostasis.
2. secondary hemostasis.
3. fibrinolysis.
In _____________ coagualtion factors will make fibrin. Strands of
fibrin are deposited on the platelet plug to reinforce and stabilize
it (the blood clot). correct answers >> secondary hemostasis.
In the ________________ stage of hemostasis, after the wound has
healed the clot is broken down and removed. correct answers
>> fibrinolysis.
Deficiency of any of the stages of hemostasis can lead to
_______________. Excess production of these stages can result in
________________. correct answers >> --bleeding or
hemorrhage.
--life-threatening thrombosis or clotting.
Is this normal coagulation or a bleeding disorder?
1. bleeding starts
2. vessels constrict
3. platelet plug
4. fibrin clot correct answers >> normal.
Is this normal coagulation or a bleeding disorder?
,1. bleeding starts
2. vessels constrict
3. incomplete platelet plug
4. incomplete formation of fibrin clot correct answers >>
bleeding disorder.
What are the 2 key players in primary hemostasis? correct
answers >> blood vessels and platelets.
After an injury, the damaged vessels initiate hemostasis by
________________. correct answers >> Contraction of the
vessels (vasoconstriction)
-Minimizes blood flow into wound area.
-Brings hemostatic components (platelets and coagulation
factors) closer to vessel wall.
-Occurs immediately and lasts a short time.
Central cavity through which blood flows is called the
_______________. correct answers >> lumen.
_______________ cells line the lumina of blood vessels. It in turn is
coated with complex protein and carbohydrate substances called
glycocalyx.
The middle layer of blood vessels is mainly smooth muscle cells,
but also contains _____________. correct answers >>
Endothelial.
, collagen fibers.
Damaged endothelial cells play a large role in initiating
hemostasis. They produce and secrete ______________ which aids
in platelets in the intial stage of primary hemostasis. correct
answers >> von Willebrand factor (vWF).
____________ cells produce tissue factor that is released during
vessel injury. They are neg charged (repelling _______________).
--Expose collagen that secrete platelet activating factor.
--Release plasminogen activator inhibitor, which inhibits
fibrinolysis. correct answers >> endothelial
platelets and proteins.
*KNOW THIS*
Platelets are produced in the bone marrow. List the maturation
stages of platelets from stem cell all the way to mature platelets.
correct answers >> Stem cell
CFU-GEMM
BFU Mk or BFU Meg
CFU Mk or CFU Meg
MK1 (Megakaryoblast)
MK 2 (Promegakaryocyte)
MK 3 (Megakaryocyte)
