Q

What are the time periods for the 3 stages of wound healing?

A
  1. Inflammatory = 0 days - 3 days
  2. Proliferative = 3 days - weeks
  3. Remodeling = 1 week - 6 months

*memory: If you take a week (7 days) and split it in half, you get the layout…. 0-3, 3-7, and 7+

Q

Why does vitamin C deficiency cause delayed wound healing?

A

Because vitamin C is a co-factor for the hydroxylation of proline and lysine residues on pro-collagen, so that the alpha triple helix can be made –> no hydroxylation = looser triple helix

Q

Why does zinc deficiency cause poor wound healing?

Q

What is the physiologic reason why ESR indicates inflammation?

A

Products of inflammation, like fibrinogen, coat RBCs and cause them to aggregate, which makes them heavier, so they will have a higher ESR
