Which endoscope is utilized to visually examine areas of the respiratory tract?

The bronchoscope is specifically designed for examining the respiratory tract, which includes the trachea, bronchi, and lungs. It has a thin, flexible tube equipped with a light and camera, allowing medical professionals to visualize and assess conditions within the airways. This tool is essential in diagnosing respiratory issues, taking biopsies, and performing certain procedures such as removing foreign bodies or clearing blockages.

In contrast, the gastroscope focuses on viewing the stomach and upper parts of the digestive system, while the duodenoscope is tailored for examining the duodenum, the first part of the small intestine. The sigmoidoscope, on the other hand, is used to examine the sigmoid colon and rectum. Each of these endoscopes serves a specific purpose related to their respective anatomical regions, making the bronchoscope the appropriate choice for visualizing the respiratory tract.
