Final answer:
True, injuries heal by either regeneration, which replaces damaged cells with new ones, or by scarring, which repairs with collagen-rich tissue but does not restore the original tissue structure fully.
Step-by-step explanation:
True or False: Injury heals by either regeneration or scarring?
True. When the body sustains an injury, it can heal through two primary processes: regeneration and scarring. Regeneration entails replacing damaged cells with new ones of the same type, maintaining the original structure and function of the tissue. Conversely, scarring occurs when the injury is repaired with collagen-rich scar tissue, leading to a tissue that is functionally similar but structurally different from the original. During scarring, fibroblasts produce a basket-weave pattern of collagen fibers, which can sometimes result in visible scars and does not allow for the regeneration of skin accessory structures. In summary, healing can result in the restoration of the original tissue or in scar formation, which serves as a permanent mark of repair.
