Lesson 10
How do enzymes help digestion?
Your body is a chemical factory. It
makes many kinds of chemicals.
Some of the chemicals your body
makes are called enzymes. You
could not live without enzymes.
Some enzymes help you digest your
food. They are called digestive
enzymes, and are made in glands.
Many tiny digestive glands are found
inside the digestive tract. They are
within the walls of the stomach and
small intestine.
When the glands are inside the
organs, the enzymes empty directly
into the organs.
Some digestive glands are found
outside the digestive tract.
They are the salivary glands, and the
pancreas.
The pancreas is found near the
stomach. The three pairs of salivary
glands are found near the mouth.
Enzymes from these glands enter the
digestive tract through tiny tubes.
These glands help with digestion,
even though food never touches
them.
The digestive tract, along with its
helping glands make up the digestive
system.
