This document discusses the five human senses - sight, hearing, smell, taste, and touch. It describes how each sense works and what it allows us to perceive. Sight allows us to see shapes, colors, and sizes through our eyes. Hearing allows us to hear sounds, music, and words through our ears. Smell allows us to detect odors through our nose. Taste allows us to experience flavors through our tongue. Touch allows us to feel textures, temperatures, and sensations through our skin. Each sense involves specialized organs that detect stimuli and send signals to the brain.

survive
INTERACTION. Living
things interact by touching,
moving, communicating
REPRODUCTION.
Living things reproduce
in order to make new
living things
14. The eyes are the organs of sight
(sclera)
The eyebrow, eyelids
and eyelashes protect
the eyes from sweat and
dust
The iris is the big
coloured circle at the front
of the eye
The pupil is the black part
in the centre of the iris
15. The light
gets in the
eye through
the pupil
The lens
focuses
the light
The retina
detects the
light.
The retina is
where the
image form
The optic nerve sends
information to the brain.
HOW WE SEE
17. The ears are the organs of the
hearing
Three small bones
Auditory nerve
The ear is divided into three parts:
outer ear, middle ear and inner ear
18. Sound enters
through the
canal
The eardrum
and the three
small bones
vibrate
The cochlea
turns the
vibrations into
signals
The auditory
nerve sends the
signals to the
brain
20. Olfatory nerve
Olfatory cells
Nostril
s
Nasal cavity
Smell enter your nostrils and pass into your nasal
cavity. The olfatory cells detect the smell. Then,
the olfatory nerve sends the information to the
brain.
The nose is the organ of smell
22. The tongue is the organ of taste.
The tongue is
covered in
many taste
buds.
Taste buds tell us about
the 4 different flavours.
The nerves in the taste
buds send information
to the brain.
