Factor VII
What is the function of activated protein C?

What is the main inhibitor of thrombin?
Thrombomodulin
Antithrombin
Tissue Factor Pathway Inhibitor (TFPI)
Protein C
Which of the following is a function of the fibrinolytic system?
Localizing thrombus to the site of injury
Activating platelets
Preventing the formation of clots
Promoting the formation of clots
What is the role of tissue plasminogen activator (t-PA) in the fibrinolytic system?
It is released from endothelial cells and binds to fibrin once the vessel is damaged
It inactivates plasminogen activator inhibitor (PAI)
It stimulates activated protein C to destroy plasma inhibitors of t-PA
It is a synthetic enzyme used in clinical practices
Which of the following inhibits fibrinolysis by activating thrombin-activated fibrinolysis inhibitor (TAFI)?
Thrombin
Plasminogen activator inhibitor (PAI)
Circulating plasmin
Activated protein C
What is the purpose of the coagulation cascade inhibitors?
To activate the fibrinolytic system
To influence the size and stability of clots
To prevent the production of fibrin
To promote the formation of clots
