Cornea receives the light rays and then light rays pass through the pupil and into the lens.
Iris (colored ring) is the muscle. It changes the size of the pupil when light rays pass through our pupil
The retina is filled with approximately 150 million light-sensitive cells called rods and cones.
Rods identify shapes and work best in dim light.
Cones identify color and work best in bright light. Then optic nerve sends the information to the brain.

5. Structure of skin

6. Continued The skin is the largest human organ
The three layers of skin: stratum corneum, epidermis, dermis
There is hair on our skin
Sense of touch originates in the dermis-the bottom layer of our skin
Tiny nerve endings in the dermis givesus information about the things our body touches. Information is carried through the spinal cord, which sends messages to the brain to register the feeling
Our body has about 20 different types of nerve endings. The most common receptors are heat, cold, pain, and pressure or touch receptors.
Some areas of the body are more sensitive than others because they have more nerve endings

Noises send vibrations (or sound waves) through the air into our ear canal by our outer ear. When vibrations move into our middle ear, they hit our eardrum (Stirrup is the last one), then pass into a coiled tube in the inner ear called the cochlea.
-Cochlea contains fluid and thousands of cilia, which is nerve endings like hair. Vibrations cause the cilia to move, which then send messages sent to the brain via the auditory nerve. The auditory nerve send messages to our brain then the brain decodes the messages

9. Structure of noses

10. Structure of noses Our nose has special cells to help us smell
Our nose has 2 nostrils that are divided by the nasal septum.
The nasal septum is made up mostly of cartilage, a tissue that is stiffer than muscle but more flexible than bone.
Air passing through the nasal cavity is adjusted to match body temperature
Short hairs in the nasal cavity remove dust and other particles
When air passes through a thick layer of mucous to the olfactory bulb after the nasal cavity, smells are recognized.
