What is the general function of endoscopy?

The general function of endoscopy is to visualize internal organs. Endoscopy is a medical procedure that utilizes a flexible tube with a light and camera attached, known as an endoscope, which is inserted into the body through natural openings or small incisions. This allows healthcare providers to examine the interior surfaces of organ systems, diagnose conditions, perform interventions, and guide biopsies, all while minimizing invasiveness and maintaining a clear view of the area in question. This capability is crucial for various medical specialties, such as gastroenterology, pulmonology, and urology, making endoscopy a valuable tool in modern medicine for diagnosing and treating health issues.
