An endoscope is a medical instrument that consists of a flexible tube equipped with a camera and light source, which allows healthcare professionals to visually examine the interior of a patient's body. This tool is especially useful for diagnosing and treating conditions within various organs and cavities, such as the gastrointestinal tract, respiratory system, and more. Endoscopes can be inserted through natural openings of the body, like the mouth or anus, or through small incisions, providing a minimally invasive means of observation and even intervention.

The function of an endoscope is particularly vital in modern medicine as it aids in procedures such as biopsies, where a small sample of tissue is taken for further analysis, or in the removal of foreign objects. Its flexibility allows it to navigate through complicated anatomical paths, which is essential for effective examination and treatment.

In contrast, the other options describe devices that serve different purposes in patient care. Blood pressure monitors are designed specifically to gauge blood pressure levels, heart rate monitors focus on cardiovascular metrics, and machines providing oxygen support are crucial for respiratory assistance. Each of these devices supports different aspects of patient monitoring and treatment, but they do not offer the visual examination capabilities provided by an endoscope.
