Scars form during tissue repair because collagen replaces normal tissue architecture
the verdict
SUPPORTED
the evidence backs this
confidence 81/100
Scars form during tissue repair primarily because fibroblasts deposit excess collagen and extracellular matrix proteins, which replaces the normal, organized tissue architecture.
