Understanding Blood Clotting Process

What is the process of blood clotting known as?

• Haemostasis

• Thrombosis

• Coagulation

• Fibrinolysis

Which enzyme is released by the damaged blood vessel during thrombosis?

• Thrombin

• Fibrinogen

• Thromboplastin

• Prothrombin

What role do calcium ions play in the process of thrombosis?

• They convert fibrinogen to fibrin

• They trigger the conversion of prothrombin to thrombin

• They dissolve the blood clot

• They act as a catalyst for thromboplastin

Which protein is converted into thrombin during the blood clotting process?

• Fibrinogen

• Thromboplastin

• Prothrombin

• Fibrin

What is the role of thrombin in the blood clotting process?

• It dissolves the blood clot

• It converts fibrinogen to fibrin

• It releases calcium ions

• It acts as a structural protein

What is the final insoluble protein that forms a mesh during blood clotting?

• Thrombin

• Fibrinogen

• Fibrin

• Prothrombin

What is trapped within the fibrin mesh to form a blood clot?

• White blood cells and plasma

• Platelets and red blood cells

• Calcium ions and thromboplastin

• Prothrombin and thrombin

Which of the following is NOT involved in the chemical cascade of thrombosis?

• Thromboplastin

• Calcium ions

• Insulin

• Thrombin

What is the initial trigger for the blood clotting process?

• Release of fibrinogen

• Damage to a blood vessel

• Increase in blood pressure

• Decrease in body temperature
