They "filter" - remove - undesirable components (wastes) from the bloodstream.
Explanation:
ALL kidneys are biological filters. A "filter" is any mechanism that selectively passes or retains something. It may be light or sound wavelengths, particles, or chemical elements.
Kidneys selectively remove waste product compounds from the bloodstream to prevent a toxic (deadly) accumulation of them in the system.
