viscera, bowels
腑 centers on the internal organs of the body, especially the digestive tract: the viscera or bowels.
腑 combines ⺼ (flesh, body part) with 府, which likely contributes the sound フ. The character refers to internal organs.
The flesh radical ⺼ on the left hints at body parts, and 府 on the right looks like a storehouse. Picture the bowels as the body's internal storehouse for processing food.
For フ, imagine a full stomach after eating: full -> フ, and the viscera are full of digested food.
