Question

What is the final stage of healing that begins about 3 weeks to 6 months after injury? During this stage, the collagen is remodeled, new collagen tissue is deposited, and the scar becomes a flat, thin, white line.

A.Maturation phase
B.Microbial
C.Granulation tissue
D.Regeneration

Answer 1

The final stage of healing that involves collagen remodeling and scar maturation occurring from 3 weeks to 6 months after an injury is known as the Maturation phase.

Step-by-step explanation:

The final stage of healing that begins about 3 weeks to 6 months after injury, where collagen is remodeled, and the scar becomes a flat, thin, white line is known as the Maturation phase. During this phase, fibroblasts replace the lost collagen and extracellular material from the injury, resulting in the formation of granulation tissue, and new blood vessels are created through angiogenesis. Ultimately, the collagen fibers are laid down in a more organized manner and the wound undergoes contraction, leading to a mature scar.
