Organ Name + 脏
The character 脏 (zàng) has a second pronunciation and meaning distinct from 脏 (zāng, dirty). When pronounced zàng, it refers to internal organs of the body and appears in medical compound words like 心脏 (heart), 肝脏 (liver), and 肾脏 (kidney). It is not used independently but always as part of an organ compound.
