Digestive and Nervous Systems

Nervous System

• Controls all other body systems• The brain is the core of the system – it collects

information and makes decisions

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

Digestive System

• Your body needs materials & energy to stay alive & grow.

• You get this energy from the food you eat.

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.

• 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.

• Any remaining food that is not digested turns into waste.

• Waste is then expelled from the body.
