Minor Injuries - Wounds, fracture and dislocation

Question 1

Step one pathophysiology of wound healing

Answer 1

Hemostasis - Vasoconstriction occurs and the fibrin forms a cross-link (prevent pathogens in and blood out)

Question 2

Step two pathophysiology of wound healing

Answer 2

Inflammation (3 hrs) - The body sends macrophages which go through phagocytosis to fight infection. Vasodilation occurs

Question 3

Step three pathophysiology of wound healing

Answer 3

Proliferative (2-3 days) - fibroblast cells enter, collagen deposition to replace damaged fibrin and dermis contracts (close the wound)

Question 4

Step four pathophysiology of wound healing

Answer 4

Remodelling - wound matures, collagen rearranged
