The nervous system controls all other body systems through the brain which collects information and makes decisions, and the spinal cord which transmits messages between the brain and body. The digestive system breaks down food in the mouth, stomach, and intestines so nutrients can be absorbed and used for energy and growth, while waste is expelled. Both systems work together to keep the body functioning.

1. Digestive and Nervous Systems

2. Nervous System
• Controls all other body systems
• The brain is the core of the system – it collects
information and makes decisions

3. Nervous System
• The spinal cord is the main pathway for
messages between the brain and the rest
of the body.
• The nervous system sends messages
from your sense organs to your brain

4. Digestive System
• Your body needs
materials & energy to
stay alive & grow.
• You get this energy
from the food you eat.

5. Digestive System
• Digestive system breaks down food so it
can be used by the body.
• Begins with your mouth when you
chew.
• Then food enters the esophagus and
goes to the stomach.
• In the stomach food mixes with
chemicals.

6. • When it leaves the stomach it goes into the small
intestine.
• Nutrients are absorbed by the body.
• In the large intestine water is removed from the food
and taken to the body.

7. • Any remaining food that is not digested turns into
waste.
• Waste is then expelled from the body.
