Final answer:
Flushing out a wound or cavity with a solution is called irrigation, often used in medical procedures for cleaning purposes. Solid solutions, such as dental amalgams, can also serve a similar purpose by filling cavities and are considered alloys.

These solid solutions are known as alloys and have different properties than the pure metals they are made from
