Blood Coagulation Process Quiz

What is the first stage of the blood coagulation process?

• Platelet Aggregation

• Coagulation Cascade

• Vasoconstriction

• Intrinsic Pathway

What happens during the platelet aggregation stage?

• Blood vessels narrow

• Platelets adhere to the injury site and clump together

• Fibrinogen converts to fibrin

• Blood vessels are damaged

What is the result of the coagulation cascade?

• Narrowing of blood vessels

• Platelet clumping

• Conversion of fibrinogen to fibrin, forming a stable clot

• Activation by external trauma

Which pathway is activated by damage to blood vessels?

• Extrinsic Pathway

• Coagulation Cascade

• Vasoconstriction

• Intrinsic Pathway

Which pathway is activated by external trauma to tissues?

• Intrinsic Pathway

• Extrinsic Pathway

• Platelet Aggregation

• Vasoconstriction

What is the purpose of vasoconstriction in the blood coagulation process?

• To activate clotting factors

• To reduce blood flow

• To convert fibrinogen to fibrin

• To adhere platelets to the injury site

What does the activation of clotting factors lead to?

• Narrowing of blood vessels

• Platelet adherence

• Formation of a stable clot

• External trauma activation

Which stage involves the narrowing of blood vessels?

• Coagulation Cascade

• Platelet Aggregation

• Vasoconstriction

• Extrinsic Pathway

What is the main function of the intrinsic pathway?

• Activated by external trauma

• Activated by damage to blood vessels

• Converts fibrinogen to fibrin

• Reduces blood flow

What is the main function of the extrinsic pathway?

• Activated by damage to blood vessels

• Activated by external trauma to tissues

• Narrowing of blood vessels

• Platelet clumping
