What component forms the scar tissue typically found in damaged mammalian hearts?
Answer
Fibrous connective tissue
When the heart muscle is damaged in mammals, the resulting repair involves forming a scar composed of fibrous connective tissue, which is the key difference compared to the newt's scar-free regeneration.
