First, food is chewed in
the mouth, and mixed
with saliva produced
by the salivary
glands.

chewed, soft food is
formed.

• moves down the
pharynx and the
oesophagus, and
passes into the
stomach.

gastric juices in
the stomach.
This produces a thick
liquid called chyme.

5. • Finally, the chyme leaves
the stomach and reaches
the small intestine.
• It mixes with juices from
the intestine, the
pancreas and the liver.
Allthe substances which
