Stool of a person is whitish grey coloured due to malfunction of which of the following organs?

  1. Pancreas
  2. Spleen
  3. Kidney
  4. Liver

Answer

(4) Liver

Solution

As per NCERT, bile secreted by the liver contains bile pigments (bilirubin and biliverdin).

⇒ Derivatives of bile pigments in the intestine give the faeces their normal yellowish-brown colour.

∵ In liver malfunction (e.g. jaundice, hepatitis) or blockage of the bile duct, bile pigments do not reach the intestine.

∴ The stool becomes whitish grey (clay-coloured) due to malfunction of the liver.

Answer: (4)
