Ambulatory Surgery Centers Practice Test

Endoscopy lets you see inside the body without making large surgical cuts. It uses a scope inserted through natural openings or small access points to visualize hollow spaces, so it’s used to look inside organs and body cavities such as the digestive tract (esophagus, stomach, intestines), the bladder, or the airways. This is why the best description is looking inside organs or body cavities. The other options refer to external surfaces (skin) or solid structures (bones) or vessels, which aren’t the typical targets of endoscopic visualization.
