Question

Cutaneous wound healing is the process of epithelial cell regeneration and formation of connective tissue scar formation. Healing by _____ intention occurs when the wound covers a large surface area (e.g., burns). Healing by _____ intention occurs when sides of the wounds can be approximated (i.e., surgical wound, laceration).

Answer 1

Answer:

The best answer to your questions, would be thus:

Cutaneous wound healing is the process of epithelial cell regeneration and formation of connective tissue scar formation. Healing by second intention, occurs when the wound covers a large surface area (e.g., burns). Healing by first intention occurs when sides of the wounds can be approximated (i.e., surgical wounds, lacerations)

Explanation

As the text says, a second intention healing is defined as the type in which a large portion of tissue has been lost, be it due to a burn, or loss of actual tissue, among other reasons, and in which the healing process requires the skin to regenerate the layers that have been lost. In this case, the edges of the wound are not close to one another, and thus cannot close seamlessly.

In first intention healing processes, there is a loss of continuity of the skin, mostly because of a cut, but the edges of the wound are close enough to knit them together, and there is no need for tissue regeneration to cover the wound. The healing is literally a knitting of the skin to recover continuity.
