Hemostasis
78
How many stage are there in coagulation/hemostasis
4 stages
79
- Blood vessels and platelets respond to injury
- blood vessels constrict to slow the flow of blood to the injured are (vessel spasm)
- platelets become sticky; clump together (platelet aggregation) and adhere to the injured vessel wall (platelet adhesion) to form a temporary platelet plug to stop bleeding
Stage 1 (primary hemostasis)
80
- blood vessels constrict to slow the flow of blood to the injured are
vessel spasm
81
when platelets become sticky and clump together
platelet aggregation
82
when platelets adhere to the injure vessel wall
platelet adhesion
83
- activation of coagulation cascade that initiate formation of fibrin strands to strengthen the platelet plug by forming a fibrin clot
Stage 2 (Secondary hemostasis)
84
activation of this initiate formation of fibrin strands to strengthen the platelet plug by forming a fibrin clot
coagulation cascade
85
activation of coagulation cascade initiate formation of _______ _________ to strengthen the platelet plug by forming a fibrin clot
fibrin strands
86
activation of coagulation cascade initiate formation of fibrin strands to strengthen the platelet plug by forming a ______ ____
fibrin clot
87
- the last factor in the coagulation cascade (Factor XIII) stabilizes the fibrin clot
- this produces retraction (tightening of the clot)
stage 3
88
- after the injury to the blood vessel has healed; the process of fibrinolysis degrades the fibrin clot into fibrin degradation products (FDP's)
Stage 4
89
- after the injury to the blood vessel has healed; the process of _________ degrades the fibrin clot into fibrin degradation products (FDP's)
fibrinolysis
90
what is the meaning FDP's
fibrin degradation products
91
bulge formed by a weakness in the wall of a blood vessel; usually an artery that burst and cause severe hemorrhage.
Aneurysm
92
hardening of the artery walls contributing to aneurysm or stroke
arteriosclerosis
93
form of arteriosclerosis characterized by accumulation of lipids and other materials in the walls of arteries causing the lumen of the vessel to narrow and stimulate clot formation

embolism
95
inflammation of the vein wall causing pain and tenderness
phlebitis
96
obstruction of a blood vessel by a stationary blood clot
thrombosis
97
swollen peripheral veins caused by damage valves allowing backflow of the blood causing edema (swelling) in the tissues

98
swelling in the tissues
edema
99
