entrails, viscera, bowels
臓 centers on the internal organs of the body: the entrails, viscera, and bowels. It refers to the soft, vital parts inside the torso.
臓 combines the flesh radical ⺼ with 蔵, which likely contributes the sound ゾウ and carries a sense of storing or hiding, fitting the idea of organs stored inside the body.
The left side ⺼ is flesh, and the right side 蔵 suggests something stored away. Picture the internal organs as flesh stored inside the body's cavity.
For ゾウ, imagine a zookeeper examining the entrails of an animal: zoo -> ゾウ, and the organs are stored inside.
