Question

Bile pigments are formed in
A. Liver
B. Spleen
C. Every body part
D. Both A and B

Answer 1

Hint: Bile is produced from the second largest organ of the human body. The presence of bile pigments in bile helps to break down and digest the fat into fatty acids in the small intestine and this process is known as Emulsification.

Complete answer:
The decomposition of worn out RBCs is brought mainly in both the liver and spleen. It contains Kupffer cells which degrade the old worn out RBCs and metabolize haemoglobin into two components namely, heme and globin. The globin is further broken down to be used as an energy source while the iron containing heme group is converted into bile pigment bilirubin.
Bile is a fluid that is produced and released by the liver and it is stored within the gallbladder. Bile pigments are present in bile. It helps in the process of digestion. The function of bile is to break down the fats into fatty acids and carry them into the body by the digestive tract.
Not all the body parts are responsible for the formation of bile pigments. Only Liver and spleen plays a major role in the formation of bile pigments.

Hence, the correct answer is option (D).

Additional information:
Bile is mainly made up of water, but it also contains bile pigments, bile salts, certain fats, and cholesterol in it. The production of bile from the liver is stored and concentrated in the gallbladder. Then it is released into the small intestine to break down and absorb fats from food.

Note: The most important bile pigments such as the green pigment biliverdin and the reddish yellow pigment bilirubin are highly found in the bile of man and carnivorous animals.
