What does lavage primarily involve?

Lavage primarily involves the washing out of an organ, which is commonly performed to remove toxins, debris, or unwanted substances from the body. This medical procedure is often applied in contexts such as gastrointestinal lavage, where the stomach is flushed to expel contents, or in other systems where it may be necessary to cleanse an area to ensure proper function or to prepare for further treatment.

In medical practice, lavage plays a crucial role in various procedures, such as irrigation during surgeries or cleansing before diagnostic tests. The focus is on the removal of harmful materials, which is critical for patient health and safety. This distinguishes lavage from the other choices, which deal with different aspects of medical assessment and treatment but do not relate to the concept of washing out an organ.
