The Human Digestive System
- Mouth; the food is chewed up by teeth and mixed with
saliva. Which contains an enzyme which breaks down
starch.
- stomach; this is a muscular bag which
contains acid to kill bacteria
- This is a long tube leading from the mouth to the anus in
which digestion takes place. Indigestible waste is ESESTED
through the anus.
- small intestine; The pancreas pours more enzymes into the small
intestine which also provides its own enzymes to break down all the
food into small soluble molecules . all products of digestion are
absorbed into the blood stream here.
- large intestine; by the time the remains of the food get
here they are very wet and sloppy. The large intestine
reabsorbs all the water from this mess leaving fairly dry
indigestible faeces to be egested (released) from the
body.
