The statement that surgical implants can be either tissue or man-made devices placed inside the body is accurate because it encompasses the broad range of materials and purposes for which implants are used. Surgical implants are designed to replace or support damaged biological structures, and they can be derived from biological sources, such as tissues from human donors or animals, as well as man-made materials like metals, ceramics, or polymers.

This definition reflects the versatility of surgical implants in various medical fields. For instance, they can be used in orthopedics (like hip or knee replacements), cardiac applications (such as stents and pacemakers), and reconstructive surgeries, which may not involve solely cosmetic purposes. The ability to use both biological and artificial materials enhances the effectiveness and applicability of implants in diverse medical situations.

The other options do not accurately describe the scope of surgical implants. They do not cover the full range of applications and materials used in surgical implants, focusing unnecessarily on specific types or limited uses.
