• erythrocytes

What is hemostasis?

• process which causes bleeding to stop and healing a wound

What converts fibrinogen to fibrin?

Correct order of coagulation factors:

• thrombin - prothrombin - fibrin - fibrinogen

• prothrombin- thrombin - fibrin - fibrinogen

• prothrombin- thrombin - fibrinogen - fibrin

Why is collagen important:

• helps RBC's stick together to heal a cut

• it removes the clot when the vessel is fully healed

• it is not important ha

• activates platelets to stick together

Which of these forms an insoluble clot?

• platelets

• fibrin

• thrombin

• collagen
