AP exam 17 and 18

How does fibrinogen change during coagulation?

• Fibrinogen levels remain unchanged during coagulation.
• Fibrinogen is broken down into platelets during coagulation.
• Fibrinogen is converted into prothrombin during coagulation.
• soluble plasma protein convertes into insoluble fibrinogen during coagulation.

What role does vitamin K play in coagulation?

• Vitamin K helps in the absorption of calcium in bones.
• Vitamin K is essential for the production of red blood cells.
• Vitamin K is needed to synthesize four coagulation factors

• Vitamin K is primarily responsible for energy production in cells.

What molecules are involved in dissolving clots or preventing clot formation?

• Plasmin and Heparin

• Vitamins and minerals
• Platelets and fibrinogen
• Red blood cells and white blood cells

is a fibrin-digesting enzyme

Platelets do not adhere to prostacyclin-coated endothelium

• Thrombin
• Plasmin
• Fibrinogen
• Collagenase

(from basophils and mast cells) interferes with formation of prothrombin

activator

• warfarin
• aspirin
• vitamin K
• heparin

deactivates thrombin before it can act on fibrinogen

• Fibrin
• Prothrombin
• Thromboplastin
• Antithrombin

Prevents Blood clots

• Antiplatelets
• Thrombolytics
• Vasodilators
• Coumarin, warfarin, Aspirin, Medicinal leeches,Snake venom from vipers

What is a thrombus?

• A thrombus is a type of white blood cell.
• A thrombus is a medication used to dissolve clots.
• A thrombus is a type of blood vessel.
• A thrombus is a blood clot that forms in a blood vessel.

clot that develops and persists in unbroken blood vessel

• embolus
• thrombus
• hematoma
• coagulum

thrombus freely floating in bloodstream

• embolus
• thrombus
• plaque
• clot
