Question

Which type of wound healing occurs when wound edges are not approximated and healing occurs from the bottom up

Answer 1

The type of wound healing you are describing is known as **secondary intention**. In secondary intention healing, the edges of the wound are not approximated (i.e., they do not come together). Instead, the wound heals from the bottom up and sides inward, which often leads to a larger scar and a longer healing time compared to primary intention, where wounds are closed directly (e.g., with sutures or staples). Secondary intention healing is typical in wounds that are too large or infected to be closed directly.
