臟

“Organs of the body”, as in 五臟 (오장, “the five viscera” – heart, liver, spleen, lungs, and kidneys in traditional East Asian medicine).

Phono-semantic compound:

肉 (육, “meat, flesh”) – indicates the meaning (a body part);

藏 (장, “to store, to conceal”) – provides the sound.

The use of 藏 (to store) also reflects the concept in traditional Chinese medicine that organs “store” vital energies and substances.

It appears in key medical and anatomical terms like 內臟 (내장, internal organs) and 五臟 (오장, the five viscera).
