The document summarizes the stages of digestion, including chewing food in the mouth, food moving through the esophagus into the stomach where it mixes with gastric juices to form chyme, and finally the chyme leaving the stomach and entering the small intestine where it mixes with juices from the intestine, pancreas, and liver to separate out all the substances needed. The liver is noted as the only organ able to regenerate itself, allowing part of one person's liver to be donated to another.

First, food is chewed in
the mouth, and mixed
with saliva produced
by the salivary
glands.
Gradually, a mass of
chewed, soft food is
formed.

3. • Then, this food
• moves down the
pharynx and the
oesophagus, and
passes into the
stomach.

4. NEXT, it mixes with
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
we require have now
been separated.

6. .
The liver is the only organ
that can regenerate itself
thus making it possible
for one person to donate
part of their liver to
another person.

7. • Pancreas makes pancreatic
juices contaning digestive
enzimes.
