• Nerves send these signals throughout the body.

7. THE FUNCTIONS OF THE BRAIN
• there are 100,000 miles of blood vessels in the
brain

8. THE FUNCTIONS OF THE BRAIN
• there are 100,000 miles of blood vessels in the
brain
• the brain can live for 4-6 minutes w/o oxygen,
5-10 minutes there is permanent damage

9. SIZE OF THE HUMAN BRAIN
• The average human brain weighs about 3
pounds.
• At birth, the human brain weighs less than a
pound.
• The human brain reaches its full size at about
6 years of age.
• Humans have the largest brain to body size.
