HEMOSTASIS INTRO

Question 1

process involved in formation of fibrin clots

Answer 1

Coagulation

Question 2

result of well-regulated processes which maintains blood in a fluid state in normal

Answer 2

Hemostasis

Question 3

hemostasis involves?

Answer 3

vascular wall w/ lining endothelium

platelets

coagulation proteins

Question 4

primary hemostasis involves?

*steps

Answer 4

platelets and blood vessels

*brief period of vasoconstriction

platelet adhesion

platelet change shape

platelets release granule causing more recruitment

platelet aggregates and form a hemostatic plug

Question 5

secondary hemostasis involves?

*steps

Answer 5

coagulation proteins

*endothelial cells release tissue factor

tissue factor causes platelets to express phospholipid complex

phospholipid complex activates thrombin

thrombin causes fibrin polymerization

controlled bleeding, counter regulatory mech set into motion
