Physiological responses to injury

How many phases of physiological response are there?

• 2

• 3

• 4

• 5

Which phase is the first to occur after injury?

• Hemostasis

• Inflammation

• Proliferative

• Maturation

What one is not part of the inflammatory phase?

• Swelling

• Pain

• Redness

• They are all characteristics of this phase

What causes the swelling seen during the inflammatory phase?

• The impact of the injury

• Vasodilation of vessels

• White blood cell accumulation

• Bleeding

Pain is felt as a result of pressure on

• Capillaries

• Arteries

• Nerves

• Vessels

What is the correct order?

• Maturation-proliferative-hemostasis-inflammation

• Inflammation-proliferative-maturation-hemostasis

• Hemostasis-inflammation-maturation-proliferative

• Hemostasis-inflammation-proliferative-maturation

What is the purpose of the proliferative phase?

• Pulls the wound closed

• New blood vessels are formed

• Stops bleeding by clotting blood

• Repaired tissues gain strength

What is the main feature of the hemostasis phase?

• Bleeding

• Blood clot formation to prevent infection

• White blood cells fight bacteria

• Development of scar tissue

What is the correct time period for the inflammatory phase?

• Day 1-3

• Day 1-10

• Day 3-21

• Day 7-months!

The hemostasis and maturation phases can happen at the same time

• True

• False
