Question

Place the following phases of wound healing by first intention in correct order from first to last:

I. proliferation
II. remodeling
III. inflammatory


A. I, II, III
B. II, I, III
C. III, I, II
D. III, II, I

Answer 1

The correct order of phases for wound healing by first intention is Inflammatory, Proliferation, and then Remodeling, which corresponds to option C. III, I, II.

Step-by-step explanation:

When it comes to healing by first intention (also known as primary union), the phases of wound healing occur in a specific order:

1. Inflammatory
2. Proliferation
3. Remodeling

The inflammatory phase begins immediately after an injury, with the formation of a blood clot and the onset of inflammation. White blood cells move into the wound area releasing inflammatory chemicals. Next, the proliferation phase involves blood clot retraction, tissue regeneration, and collagen deposition by fibroblasts. Lastly, the remodeling phase consists of the further strengthening of tissue and scar formation. Based on the given options, the correct sequence is C. III, I, II - Inflammatory, Proliferation, Remodeling.
