Edexcel IAL Atherosclerosis and Blood Clotting Quiz

What forms a mesh in blood clotting, trapping bundles of blood cells?

• Platelets

• Thrombin

• Fibrin

• Thromboplastin

What can lead to the formation of a temporary plug in blood clotting?

• Smooth blood vessel walls

• Platelets clumping together

• Decreased blood pressure

• Lack of clotting factors

How can thrombosis contribute to cardiovascular disease?

• By promoting blood circulation

• By decreasing blood clotting

• By restricting blood flow through vessels

• By preventing blood loss from damaged vessels

What is thrombosis?

• Hardening of arteries

• Blood clot formation

• Inflammation of blood vessels

• Narrowing of veins

What does thrombin catalyze in blood clotting?

• Conversion of platelets to fibrinogen

• Conversion of fibrinogen to thromboplastin

• Conversion of fibrinogen to insoluble fibrin

• Conversion of thromboplastin to clotting factors

How does atherosclerosis impact blood flow?

• Increases blood flow

• Decreases blood flow

• Causes blood clotting

• Promotes blood circulation

What is atherosclerosis?

• Softening of arteries

• Hardening of arteries

• Blockage of veins

• Inflammation of blood vessels

What triggers the change of prothrombin to thrombin in blood clotting?

• Platelets

• Fibrinogen

• Clotting factors like thromboplastin

• Damaged blood vessels

What contributes to the narrowing of arteries in atherosclerosis?

• Low blood pressure

• Accumulation of fibrous plaque

• Increased blood flow

• Decreased blood clotting

What is the cause of atheroma formation in atherosclerosis?

• Low blood pressure

• Damaged endothelium

• Lack of cholesterol

• Excessive blood flow
