14. The Information Highway
Unit 3 Lesson 3 How Do Cells Work Together?
The Information Highway
The nervous system is made of tiny structures called nerve cells. Chains of long nerve cells make up nerves.
Nerves carry information to and from the brain, which processes information.
The spinal cord, a rope-like bundle of nerve tissue, is the main pathway for information travelling to and from the brain.

Sight and Smell
Sight
The iris is the part of the eye that gives your eye color. Light enters the eye through the pupil.
The retina at the back of the eye contains nerve cells that detect light. These nerve cells send signals to the brain.

23. Hearing and Taste Hearing Unit 3 Lesson 3 How Do Cells Work Together?
The outer ear funnels sound into the middle ear causing the eardrum to vibrate.
Tiny bones ( hammer, anvil, and stirrup) pass vibrations to the inner ear where a fluid-filled structure called the cochlea passes vibrations to tiny hairs on the nerves.
These nerves send messages about vibrations to the brain and you hear.

The Skin You’re In
Skin is a protective layer that covers the body.
Skin, fingernails, toenails, and hair are part of the integumentary system. The integumentary system protects the inside of the body.
Skin keeps germs out of the body and water in the body.
When you get too hot, sweat on the skin cools the body. When you get too cold, hair keeps your head warm.
Hair also protects your skin.
