Questions and Answers

What is the primary role of fibrinogen in relation to erythrocytes?

  • It prevents erythrocytes from aggregating during inflammation.
  • It binds to erythrocytes and causes them to sediment more rapidly. (correct)
  • It facilitates the breakdown of erythrocytes during inflammation.
  • It promotes the release of erythrocytes from bone marrow during inflammation.

Which of the following is a potential complication of acute inflammation?

  • Rapid destruction of the causative agent and inflammatory cells.
  • Progression and spread of the inflammatory process. (correct)
  • Immediate clearance of necrotic debris and edema fluid.
  • Complete restoration of the inflamed tissue to its normal state.

What is the primary mechanism by which chronic inflammation can develop?

  • Persistence of the offending agent or an immune response to self-antigens. (correct)
  • Immediate clearance of necrotic debris and edema fluid.
  • Rapid destruction of the causative agent and inflammatory cells.
  • Complete restoration of the inflamed tissue to its normal state.
