What term is used for devices that are inserted in the body?

• A. External devices
• B. Assistive devices
• C. Wearable technology
• D. Implantable devices

Answer: (D)

The term for devices that are inserted in the body is "implantable devices." These are specifically designed to be placed within the body for medical purposes, such as monitoring or treating health conditions. Examples of implantable devices include pacemakers, orthopedic implants, and drug delivery systems. Their design allows them to interact with bodily functions either to restore or enhance physiological processes or to provide therapeutic benefits directly at the site of implantation.

In contrast, external devices are used outside the body and do not require surgical insertion. Assistive devices are broader and can include any tool that aids a person in daily tasks or activities, irrespective of whether they are inside or outside the body. Wearable technology typically refers to devices worn on the body, like fitness trackers or smart glasses, but they are not implanted. Thus, "implantable devices" is the precise term for those inserted into the body.
