7. DIGESTIVE SYSTEM
• The digestive system breaks down the food that we
eat into small molecules that the body can absorb.
• Stomach and intestines are organs of digestive
system.
8.
9. THE RESPIRATORY SYSTEM
• The respiratory system absorb oxygen and relax
carbon dioxide.
• Lungs and trachea are organs of respiratory system.
15. HEALTHY HABITS
• EAT A BALANCE DIET
• EXERCISE
• KEEP CLEAN AND GOOD HIGYENE
• HAVE A GOOD POSTURE
• SPEND TIME WITH OUR FRIENDS AND FAMILY
16. EXTERNAL
• This stimuli are outside
the body.Our sense organs
capture these stimuli and
send message to brain
.EXAMPLE
• WHEN YOU GO OUT AND
IT’S VERY COLD, YOU FEEL
THE COLD AND SEND THE
INFORMATION TO BRAIN,
AND YOUR BRAIN SAY GO
TO PUT A JACKET.
INTERNAL
• Happend inside our
body.Receptor organs
recibes these stimuli,and
then send the message to
brain.The stomach is a
receptive organ because it
takes in food.
17. EXAMPLE OF EXTERNAL
WHEN YOU GO
OUTAND THE
WEATHER
ARE COLD,
AND YOU
ARE COLD
YOU SEND THE
INFORMATION TO THE
BRAIN AND THE BRAIN
SAY GO AND PUT A JACKET
AND YOU GO AND PUT
YOUR JACKET, YOUR
SCARF……..
18. • TYPES OF RESPONSE:
MOTOR RESPONSE
• Is when your muscles move
GLANDULAR RESPONSE
• Happend when a organ called gland produce a
subtance.
19. EXAMPLES OF MOTOR AND
GLANDULAR RESPONSE
MOTOR RESPONSE GLANDULAR RESPONSE
29. THE SENSE OF EARING
• The outer ear collect things.The sound pass
through the inner ear canal,the middle ear
and the three small bones.Then the sounds
reach the cochlea and the auditory canal.
31. THE NERVOUS SYSTEM
Controls our body seding,reciving and interpreting
information from old parts of our body.
The messajes travel thought nerve impulses.
32. SENSE ORGANS
RESPON TO A
STIMULUS AND SEND
IMPULSES ALONG THE
SENSORY NERVES
SENSORY NERVES
THEY CARRY
INFORMATION FROM
SENSES ORGANS AND
INTERNAL ORGANS
TO THE CENTRAL
NERVOUS SYSTEM
CENTRAL NERVOUS SYSTEM
Receives and interprets information and
produces response.Made up of:
SPINAL CORD
PRODUCES INVOLUNTARY MOVEMENTS
BRAIN
INSIDE THE CRANIUM OR SKULL.
MAKE DECISIONS AND GIVES ORDERS.
MUSCULOSKELETAL SYSTEM
INVOLUNTARY MOVEMENTS
Produce by the spinal cord.
Reflexes are fast and automatic.
VOLUNTARY MOVEMENTS
Produce the brain.
Voluntary movements are slower than
involuntary movements.
MOTOR NERVES
COORDINATES THE INFORMATION,
RECEIVES AND SENDS
IMPULSES ALONG
MOTOR NERVES.
38. MUSKULOSKELETAL SYSTEM
• LIGAMENTS:Connect bones to each other.
• TENDONS:attach muscles to the bones.
• BONES:Proect the internal organs.
• MUSCLES:Can stretch and contract.This helps
the bones to move.
