Please fill in the blanks:
Light rays from an object are refracted by the ____ and the ____ which focus the light rays onto the ____. The amount of light that reaches this light-sensitive layer is controlled by the ______ which is able to adjust the size of the _____. There are two types of light-sensitive cells, the ___, which are responsible for ___ vision in low light intensity, and the _____, which are responsible for ___vision in _____light intensity.
The image formed on the _____ is _____ and _____ than the object, but the nerve impulses that pass along the _____ nerve to the brain are interpreted so that they make sense. The ability of the brain to compare incoming information with previous experience, and to set off the correct response, is called _____.

Light rays from an object are refracted by the cornea and the lens which focus the light rays onto the retina. The amount of light that reaches this light-sensitive layer is controlled by the iris which is able to adjust the size of the pupil. There are two types of light-sensitive cells, the rods, which are responsible for peripheral vision in low light intensity, and the cones, which are responsible for color vision in high light intensity.
The image formed on the retina is inverted and smaller than the object, but the nerve impulses that pass along the optic nerve to the brain are interpreted so that they make sense. The ability of the brain to compare incoming information with previous experience, and to set off the correct response, is called visual perception.
