What is the purpose of an endoscope?

• A. To perform surgery within a cavity
• B. To examine the interior of a hollow organ or body cavity
• C. To inject medication into a body cavity
• D. To perform tissue biopsies

Answer: (B)

The purpose of an endoscope is to examine the interior of a hollow organ or body cavity. Endoscopy involves the use of a flexible or rigid tube with a light and camera, which allows healthcare professionals to visualize the interior of structures such as the gastrointestinal tract, respiratory system, and other hollow organs. This examination can help in diagnosing conditions, monitoring diseases, and guiding further medical interventions.

While some endoscopic procedures may facilitate actions like surgery, injecting medication, or performing tissue biopsies, these are secondary functions. The primary design and function of an endoscope focus on the visualization and examination of internal areas, enabling physicians to assess the health of organs and identify abnormalities. This crucial diagnostic capability is what distinguishes the endoscope's primary purpose.
