Several glands are involved in the digestion process. These include the salivary glands, glands in the stomach, and glands in the duodenum or small intestine. The liver is the largest gland involved in digestion by producing bile juice.
The pancreas is a glandular organ in the upper abdomen and acts as both the endocrine and exocrine gland. It secretes enzymes to break down the proteins, lipids, carbohydrates, and nucleic acids in food.
Pancreatic juice is secreted by the pancreas located in the visceral region and is a major part of the digestive system. It contains a variety of enzymes like trypsin, amylase, trypsinogen, chymotrypsinogen, elastase, carboxypeptidase, pancreatic lipase and nucleases. Pancreatic juice is alkaline in nature.

Question 27
Read the following passage carefully and answer the questions that follows it.

Bile juice is stored in a sac called the gall bladder, located near its organ of secretion that is the liver. The gall bladder releases the bile juice into the small intestine whenever food reaches there. Though bile juice is devoid of any digestive enzymes, it is required for the digestion of fats. The fats cannot be digested easily because they are insoluble in water and are present as large globules. Bile juice breaks down big fat droplets into smaller droplets. These are then easily digested by the enzymes released by the pancreas.

(a) Which organ secretes the bile juice?

(b) Why is digestion of fats difficult as compared to that of other nutrients?

(c) How does bile juice help in digestion of fat?

(d) Where is the digestion of fat completed?

(e) Does bile juice digest fat completely?
