When the body cannot regenerate tissue or cells after they have been destroyed, it makes scar tissue instead. The purpose of the scar tissue is to restore:
Structural integrity
Secondary intention
Primary intention
Metaplasia
The Correct Answer is A
A. Scar tissue serves to restore structural integrity to damaged areas, providing a scaffold for tissue repair, though it does not have the same functionality as the original tissue.
B. Secondary intention refers to the healing process of wounds that are not closed (such as ulcers or infected wounds), not the purpose of scar tissue.
C. Primary intention involves healing with minimal tissue loss (e.g., surgical wounds), and while scar tissue may form, the main purpose is not to restore it.
D. Metaplasia refers to the transformation of one cell type to another, not the formation of scar tissue.
