What is a body cavity search?

A body cavity search refers specifically to an intrusive inspection involving the examination of a person's body cavities other than the superficial openings like the nose, mouth, or ears. This type of search is typically conducted by trained personnel, often in the context of law enforcement and security measures, and requires adherence to strict legal and ethical standards due to its invasive nature.

By focusing on the correct definition, we can understand that the primary aim of a body cavity search is to locate hidden items or substances that may be concealed within the body, rather than simply searching for evidence or conducting a health assessment. The other options provided refer to different procedures or contexts entirely, such as evidence gathering on a vessel or inventorying personal items, which do not encompass the specific invasive nature and intent of a body cavity search.
