The cornea is like a clear glass that covers the front of the eye. The iris is the colored part of the eye. It lets just the right amount of light to enter the eye. At the center of the iris is the pupil. The pupil is a circular hole where light enters. Next to the pupil is the lens. The lens focuses the image we see onto the retina located at the back of the eye. The retina is like a “screen” where the image of the object seen is focused. The optic nerve connected to the eye sends the message to the brain to tell about the image seen. 50

Nose

Our nose helps us to smell things around us. We use it to breathe. The nose is made up of the nostrils, nasal cavity and nerves. The nostrils are the two holes of the nose. Inside the nostrils are hairs that keep dust out of the nose.When you inhale, air enters the nostrils and passes through the nasal passages and into the nasal cavity. The nasal cavity is the space behind your nose, in the middle of your face. Its walls are wet, warm, and covered with mucus, a sticky liquid. Mucus traps dusts, dirt or germs which enter the nostrils and were not filtered by the nose hairs. Inside the nasal cavity are nerves that pick up the scents carried by air. The nerves in the nasal cavity send messages to the brain which interprets what we have smelled.
