This document discusses the five senses - sight, hearing, touch, smell, and taste. It describes the organs and parts associated with each sense. The eye is described as the organ of sight, containing structures like the eyeball, iris, pupil, lens, retina and optic nerve. The ear is the organ of hearing and contains the outer, middle and inner ear. The skin is the organ of touch and has three layers - the epidermis, dermis and hypodermis. The nose contains the pituitary gland in the nostrils and is the organ of smell. Finally, the tongue contains taste buds and is the organ of taste.

6. Sight
The eye is the organ of sight. It is made up of the eyeball and
protected by the eyebrows, the eyelashes and the eyelids.
• When the light arrives at the eyeball, it goes through the
cornea, a hard and transparent shell.
• It passes through the pupil, the opening of the iris, like a
window.
• Afterwards, the light passes through the lens, which focuses
the image on the retina, at the bottom of the eye.
• The information in the retina travels to the brain through the
optic nerve.
The organ of sight is the eye and the main part of the eye
is the eyeball.
