Blood Clotting Process

What is the primary function of blood clotting?

• To dissolve blood cells

• To decrease blood pressure

• To stop bleeding by forming a clot

• To increase blood flow

What is the first step in the blood clotting process?

• Fibrinolysis

• Vascular spasm

• Coagulation cascade

• Platelet plug formation

What role do platelets play in blood clotting?

• They dissolve the clot

• They form a mesh-like structure

• They activate the coagulation cascade

• They form the initial plug

What triggers platelet activation?

• Exposure to thrombin

• Exposure to fibrin

• Exposure to collagen

• Exposure to oxygen

What is the role of clotting factors?

• To constrict blood vessels

• To dissolve fibrin

• To activate platelets

• To convert fibrinogen to fibrin

What is fibrin?

• A protein that forms a mesh-like structure

• A soluble protein in the blood

• A type of platelet

• An enzyme that breaks down clots

What is the purpose of the fibrin mesh?

• To activate more platelets

• To trap blood cells and seal the wound

• To dissolve blood cells

• To increase blood flow

What is the final step in the blood clotting process?

• Coagulation cascade

• Vascular spasm

• Platelet plug formation

• Fibrinolysis

What enzyme is responsible for breaking down the fibrin clot?

• Thrombin

• Plasmin

• Fibrinogen

• Collagen

What is the role of thrombin in blood clotting?

• To constrict blood vessels

• To activate platelets

• To convert fibrinogen to fibrin

• To dissolve the clot
