Understanding Hemostasis Processes

What is the first stage of hemostasis?

• Platelet Plug Formation

• Vascular Spasm

• Blood Coagulation

• Fibrin Formation

Which component is converted to fibrin to form clots?

• Plasminogen

• Fibrinogen

• tPA

• Thrombus

What is the role of tPA in hemostasis?

• Forms the clot structure

• Converts plasminogen to plasmin

• Adheres platelets at the injury site

• Causes blood vessel constriction

What is a thrombus?

• A clot that travels through the bloodstream

• A clot formed in a blood vessel

• A mesh formed by fibrin

• A type of platelet

During which stage of hemostasis do platelets adhere and aggregate at the injury site?

• Vascular Spasm

• Platelet Plug Formation

What is an embolus?

• A clot that forms a mesh

• A thrombus that breaks loose and travels through the bloodstream

• A type of blood cell

• A protein that dissolves clots

Which stage of hemostasis involves the formation of a fibrin mesh?

• Blood Coagulation

• Plasmin Activation

What is the function of plasminogen in hemostasis?

• Forms the clot structure

• Converts to plasmin to dissolve clots

• Adheres platelets at the injury site

Which of the following is NOT a stage of hemostasis?
