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.
