What is the role of a bronchoscope?

A bronchoscope is specifically designed for examining the respiratory tract, including the lungs and the airways. This instrument allows healthcare professionals to visualize and assess conditions affecting the respiratory system, such as infections, blockages, or tumors. Additionally, it can be used therapeutically to perform procedures like biopsy, removal of foreign objects, or localized treatments within the lungs.

The other choices pertain to different scopes and their associated areas:

• The first option relates to the examination of the colon, which is typically done using a colonoscope.

• The second option involves the visualization of the lower digestive tract, also associated with colonoscopy.

• The third option is focused on the upper gastrointestinal tract, which is examined using an endoscope or gastroscope.

Thus, the only choice that accurately describes the function of a bronchoscope is the ability to visually examine and treat areas of the respiratory tract.
