Circle the odd one.
The coiled middle portion of the small intestine which is 2.5 meters long is the ______.
The digestion of all food components is completed by the ____________ juice.
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.
