Coagulation: Set #1

Spontaneous arresting of bleeding from blood vessel:
1. vasospasm
2. viscous metamorphosis
3. hemostasis
4. fibrinolysis
5. coagulation
Platelet sticking to exposed damage blood vessel collagen:
1. vasospasm

3. fibrinolysis
4. platelet adhesion
Initial type of thrombus associated with formation in high-pressure arteries:
1. white thrombus
2. red thrombus

2. thromboxane A2 (TXA2)
3. both
4. neither
More likely associated with venous thrombi:
1. local occlusive ischemia
