Origin

This character combines the flesh radical (the left side, showing it's a body part) with a component on the right that provides a sound hint for how to pronounce it. The flesh radical immediately tells you we're talking about something inside the body, and the right component guides the pronunciation toward "jin." Together, the shape evolved to represent the kidney, one of the vital internal organs recognized in both Chinese medicine and anatomy.
