Which instrument is used to examine the inside of the body?

An endoscope is a versatile instrument specifically designed to examine the inside of the body. It consists of a long, flexible tube equipped with a light and camera, enabling healthcare professionals to view internal organs and cavities through small incisions or natural openings. This tool is particularly valuable for diagnosing and treating conditions in various areas, such as the gastrointestinal tract, respiratory system, and urinary tract.

While other instruments do serve important roles in examining specific areas, they do not provide the same level of comprehensive internal examination as an endoscope. A stethoscope is primarily used for auscultation, allowing healthcare providers to listen to the sounds of the heart, lungs, and other body sounds, but it does not visualize internal structures. An otoscope is specialized for examining the ear canal and eardrum, making it limited to ear assessments. A colonoscope is another type of endoscope designed specifically for examining the colon, but it is not as general-purpose as the endoscope. Thus, the endoscope stands out as the most versatile instrument for internal body examination.
