Question

Do kidneys play a role in the digestive system?

Answer 1

Not directly, but they do support each other

Explanation:

The Digestion System, in brief, consists of the mouth, stomach, liver/gall bladder, pancreas, and intestines (small and large).

The kidneys are part of the Urinary System which consists, in brief, of the kidneys and bladder:

And so, directly, the kidneys are not part of the Digestive System.

However, the two systems do interact. The Digestive System brings energy into the body which feeds, in part, the kidneys. The kidneys, as part of the Urinary System, support the cells of the body (including those of the Digestive System) to eliminate wastes from the blood.
