Exam 2 - Hemostasis & Disturbances of Circulation

Question 1

Normal hemostasis maintains _ _ in a fluid state and allows for the extremely rapid
formation of a localized hemostatic plug to prevent excessive _ _ after vascular
injury

Answer 1

Normal hemostasis maintains blood in a fluid state and allows for the extremely rapid
formation of a localized hemostatic plug to prevent excessive hemorrhage after vascular
injury

Question 2

Alterations in hemostasis can result in excessive coagulation (_              _) or
 deficient coagulation (_             _)

Answer 2

Alterations in hemostasis can result in excessive coagulation (**thrombosis**) or
 deficient coagulation (**hemorrhage**)

Question 3

The three major components of hemostasis are: 1.
_ _, 2. _ _, and 3. _ _

Answer 3

The three major components of hemostasis are: 1.
blood vessel wall, 2. platelets, and 3. coagulation factors

Question 4

Under normal conditions, the endothelium antagonizes clot formation. This is accomplished by mechanisms that promote _ _, _ _ platelet adhesion and aggregation, and _ _ coagulation

Answer 4

Under normal conditions, the endothelium antagonizes clot formation. This is accomplished by mechanisms that promote vasodilation, inhibit platelet adhesion and
aggregation, and inhibit coagulation
