प्रश्न
List two different functions performed by the pancreas in our body.
उत्तर
The pancreas contains both the endocrine and exocrine portions. The exocrine region secretes sodium bicarbonate and many digestive enzymes. The pancreatic amylase causes a breakdown of starch, pancreatic lipase causes a breakdown of lipids, and trypsin causes digestion of proteins The endocrine regions secrete hormones i.e. insulin and glucagon. These hormones regulate the level of glucose in the blood. Insulin decreases while glucagon increases the blood glucose level.

Read the following passage carefully and answer the questions that follow it. Bile juice is stored in a sac called, the gall bladder, located near its organ of secretion, 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 from the pancreas.
