Questions and Answers

What is the primary aim of haemostasis?

  • To dissolve blood clots
  • To accelerate blood flow
  • To increase blood pressure
  • To stop haemorrhage from damaged blood vessels (correct)

    • What is the term for the slowing or stoppage of blood flow?

  • Coagulation
  • Haemorrhage
  • Haemostasis
  • Stasis (correct)

    • What is the function of proteins created in the liver during secondary haemostasis?

  • To reduce blood flow
  • To break down blood clots
  • To increase blood pressure
  • To stabilise the platelet plug (correct)
