3. MUSCULOSKELETAL SYSTEM
ā¢ Musculoskeletal system
gives your body structure,
protection and power.
ā¢ The 206 bones of your
skeleton are the bodyās
framework.
ā¢ The 640 skeletal muscles
produce and control every
movement made by the body.
Aune Greggas
4. ā¢ The skull protects the brains.
ā¢ The backbone is made of
drum shaped bones.
ā¢ The ribs protect heart, lungs,
liver, kidneys and stomach.
ā¢ The hip bone and bones in
the feet are good for walking
and bones in the arms and
hands to grasp and to work. Skeleton has 206 bones.

Skeleton
5. Bones
ā¢ The skeleton is made of bones. Bones are
light but very strong. They make ca. 14 % of
the bodyās total weight. The deposited
minerals calcium and phosphate make
bones strong.
ā¢ The bone structure is not homogenous but
full of holes. They are provided by cress-
crossing struts each angled perfectly to
cope with stresses and strains. The more
exercise and activation the stronger the
bones. If there is lack of calcium or
phosphate in the food, the holes in the
bones will become larger and bones weaker
http://www.ucl.ac.uk/~sjjgsca/MuscleStriated.gif
Diagram of a bone. The
bones are of living material. If
there is too little calcium in the
food, the body begins to use
the calcium in the bones.
6. Bones are living tissue
ā¢ The bones are living tissue.
ā¢ The bones grow near the
end of the bone. Some
bones have jelly-like bone
marrow.
ā¢ In each bone there are
special cells called
osteoblasts that can renew
the bone structure.
If a bone breaks, it
can be healed in a
couple of months.
http://www.foothealthfacts.org/footankleinfo/Bone_Healing.htm
7. Joints
ā¢ The bones join to
each other in many
different ways.
ā¢ The basic joints
are: shoulder,
elbow, hand, hip,
knee, ankle and
spine.

8. Tendons
ā¢ Tendons are cords that tie a
muscle to a bone or muscle
to another muscle. Most
are rope-like bundles of
fibers.
ā¢ Finger movements are also
based on movements in the
forearm connected with
long tendons to the fingers.
Muscles and tendons

http://en.wikipedia.org/wiki/Hand
9. Achilles tendon
ā¢ The most known
tendon is Achilles
tendon, which pulls up
the heel at the back.
ā¢ Also the toes are
connected to the feet
muscles with long
tendons.
http://en.wikipedia.org/wiki/Achilles_tendon
Achilles tendon
10. Ligaments
ā¢ Ligaments are cords attached
to bones on either side of a
joint to strengthen it.
ā¢ They are made up of bundles of
collagen and a stretchy
substance called elastin.
ā¢ Ligaments also support various
organs, including the liver,
bladder and uterus (womb).
Ligaments
connect bones to
other bones to
form a joint. In the
picture ligaments
in the knee.
http://en.wikipedia.org/wiki/Knee
11. Durability
ā¢ When the human
being dies and the
muscles, tendons and
ligaments decay, all
what will be left of her
are the loose bones
and teeth.
TimothyD.Whute,PieterA.Folkens,AcademicPress
12. Cartilage
ā¢ Cartilage is a rubbery substance. There are
three different types of cartilage in the body:
ā¢ Hyalin cartilage is used in joints between bones
to cushion them against impacts.
ā¢ Fibrous cartilage is really tough and it is found
between the bones of the spine and in knee.
ā¢ Elastic cartilage is very flexible and it is used in
airways, nose and ears.
13. Muscles
ā¢ Muscles are
special fibers
that contract
(tightens) and
relax to move
parts of the
body.
http://www.ucl.ac.uk/~sjjgsca/MuscleStriated.gif
Diagram of a muscle.
14. Flexor and extensor muscles
ā¢ Muscles can shorten
themselves, but they
cannot make themselves
longer, so the flexor
muscle that bends a joint
is always paired with an
extensor muscle to
straighten it again.
http://scienceblogs.com/clock/upload/
2006/06/muscle%20contraction.jpg
Muscles can only shorten.
15. Different types of muscles
There are three types of muscles:
ā¢ skeletal muscles
ā¢ smooth muscles
ā¢ cardiac muscles.
http://en.wikipedia.org/wiki/Muscle
16. Skeletal muscles 1
ā¢ There are 640
skeletal muscles in
the body.
ā¢ The skeletal muscles
are voluntary
muscles.
ā¢ Most skeletal muscles
are arranged in pairs.
http://en.wikipedia.org/wiki/File:Muscles_anterior_labeled.png
18. Smooth muscles
ā¢ Smooth muscles are involuntary muscles. They
work automatically.
ā¢ The muscles of intestines are smooth muscles.
They move the food forward in the intestines.
ā¢ Even if the smooth muscles cannot be affected
by will, they become slower with depression.
ā¢ Caffeine has an opposite effect to the intestine
muscles.
19. Cardiac (heart) muscle
ā¢ The cardiac muscle has
muscle cells that work in a
similar way to nerve cells,
transmitting the signals for
muscle contraction to
sweep through it.
ā¢ The heart is an involuntary
muscle.
http://en.wikipedia.org/wiki/Heart
Heart
20. Energy production
The energy needed to contract the muscle can
be received by:
ā¢ anaerobic alactate energy production
ā¢ anaerobic lactate energy production
ā¢ aerobic energy production.
21. Anaerobic alactate
ā¢ In anaerobic alactate
energy production the
body is using the
adenosine triphosphates
(ATP) which have been
collected to the muscle
cells. Their amount is not
large enough to continue
the work for a long time.
Adenosine triphosphate
(ATP)
22. Anaerobic lactate
ā¢ In anaerobic lactate
energy production ATP is
produced from
carbohydrates, glycogen
or glucose. However it
leaves in the body milk
acid which makes that the
muscles become tired and
begin to ach.
Glycogen can storage as
many as 30.000 glucose
units for energy production
in the body.
http://en.wikipedia.org/wiki/Glycogen
23. Aerobic
ā¢ In aerobic energy
production the energy (ATP)
is produced from carbon
hydrates, fats and proteins
with the help of oxygen.
ā¢ It can continue as long as
there are energy storages
and oxygen. However the
production ability is limited.
http://en.wikipedia.org/wiki/Walking
24. Aerobic exercise
ā¢ Aerobic exercises improve
blood circulation and lower
blood pressure.
ā¢ They help in making heart
stronger. By pumping more
blood in the heart they
reduce the risk of heart
attacks. They also increase
the red blood count.
Aerobic
exercises:
- Walking
- Hiking
- Running
- Cycling
- Swimming
- Playing tennis
25. BLOOD CIRCULATION
ā¢ Each of the bodyās 600
billion cells need
oxygen. They get it
through blood.
ā¢ Blood circulates
continuously round
and round the body
through blood vessels.

v=ABTvNR59K5Q&feature=player_detailpage
You can look at the video of blood
circulation in YouTube by

26. Blood vessels
ā¢ Blood vessels are an
intricate series of tubes.
On the other side there
is the heart with its large
veins and arteries and
on the other side there
are small capillary
vessels.
http://en.wikipedia.org/wiki/Cardiovascular_system
27. Heart
ā¢ The heart is a powerful
pump. It is made of a
muscle.
ā¢ It has two sides, weaker
right side and stronger
left side.
ā¢ Both of them has two
chambers: a ventricle
and an atrium.
Heart
http://en.wikipedia.org/wiki/Cardiovascular_system
Ā
28. Pulmonary circulation
ā¢ In the blood circulation
there are two different
parts. The smaller of them
is the pulmonary
ā¢ circulation.
ā¢ In it the blood (blue) which comes from
different parts of the body is sent
through the right ventricle and right
atrium to the pulmonary arteries.
http://en.wikipedia.org/wiki/Pulmonary_circulation
29. Exchange of gases
ā¢ Pulmonary arteries take the blood to the
lungs where the red blood cells give away
carbon dioxide and get oxygen.
ā¢ Carbon dioxide is a product of energy
consumption in the body.
ā¢ The blood with carbon dioxide is bluish.
When carbon dioxide is changed to oxygen,
the color of the blood becomes red.
30. Systemic circulation
ā¢ The larger unit is the systemic circulation.
ā¢ In it the blood with high oxygen from the
lungs goes through the left ventricle and left
atrium and from there intrudes with a high
pressure through the aorta and larger arteries
to the heart, to the brain, to the intestines, to
the hands and to the feet and to the muscles
all the way to the most distant
capillary arteries.
http://en.wikipedia.org/wiki/Capillary
31. Pulse
ā¢ The heart pulse is ca. 60-70 times a minute.
ā¢ On an average it takes less that 90 seconds for
the blood to circulate through all the blood
vessels in the body.
ā¢ If the heart stops, first the cells in the brain and
then the cells all over the body begin to die.
ā¢ After some minutes it is not any more possible
to resuscitate a person.
32. Blood
ā¢ Blood is the liquid that
circulates around the
body.
ā¢ It contains different
types of cells:
ā¢ red cells
ā¢ white cells
ā¢ and platelets.
http://en.wikipedia.org/wiki/White_blood_cell
ThereĀ areĀ threeĀ differentĀ
typesĀ ofĀ cellsĀ inĀ theĀ blood:Ā
redĀ cells,Ā whiteĀ cellsĀ andĀ
platelets.
33. Blood cells
ā¢ Red cells are the carriers
of oxygen and carbon
dioxide. They include iron.
ā¢ White cells are important
when the body fights
against infections.
ā¢ Platelets make blood clots
to stop bleeding.

34. Blood groups
There are four
blood groups:
ā¢ A, B, AB, O.
ā¢ Each one of
them can be
either Rh
positive (+) or
Rh negative (-). http://en.wikipedia.org/wiki/Blood_type
35. HEALTH PROMOTION
ā¢ Physical work and physical
training help to keep the
body in a good condition.
ā¢ Exercise and low fat food
keep the blood vessels open.
ā¢ Also vegetarian food with
plenty of fruits, nuts, seeds
and beans helps in
maintaining good health.
AuneĀ Greggas
36. Main death reasons
ā¢ In the western world one of the
most usual death reasons are the
heart and blood vessel diseases.
ā¢ Obesity, diabetes and smoking
increases their possibility.
ā¢ The possibility for a teen age
smoker to die in heart attack (if he
continues to smoke) is three times
larger than for the nonsmoker.

37. Smoking and blood circulation
ā¢ Nicotine in tobacco
contracts arteries,
especially capillary
arteries.
ā¢ Smoking also increases
fat and cholesterol
formation on the walls
of the veins.

38. Necrosis as a result of smoking
ā¢ Fat and cholesterol
formations in the
veins and the
contraction of arteries
cause that less blood
reaches distant areas
as for example hands
and feet and might
result in necrosis.

39. Skin wrinkles
ā¢ The blood circulation
is also less in the cells
on the skin of the
face.
ā¢ A smoker looks much
more older than a
non smoker, because
the smoker has much
more wrinkles.

40. Changes in the veins
ā¢ Smoking can be
seen quite
quickly in the
veins.
ā¢ The veins of the
smoker collect
much more fat
and they do not
look healthy.
These veins belong to persons who
died in a car accident. The 32 old was a
smoker, the 34 old was a nonsmoker.
Archaive/ETRA-liitto
41. Blood pressure
ā¢ The fat cholesterol deposits in the veins and
constriction in the capillary arteries increase
the blood pressure.
ā¢ The higher the blood pressure the more
power is needed to get blood to the body.
ā¢ Also caffeine and salt increase blood pressure.
ā¢ High blood pressure in itself is a danger and
increases heart attacks and strokes.
42. Classification of blood pressure
Category systolic, mmHg diastolic, mmHg
Hypotension < 90 < 60
Normal 90 ā 120 and 60 ā 80
Prehypertension 121 ā 139 or 81 ā 89
Stage 1
Hypertension 140 ā 159 or 90 ā 99
Stage 2
Hypertension ā„ 160 or ā„ 100
43. Exercise
ā¢ Exercise is health
promoting.
ā¢ Even if the blood
pressure is high while
the exercise continues,
the blood pressure
after the exercise tend
to be lower than
without exercise. Aune Greggas
44. Why smokers are less fit
than non-smokers?
ā¢ To achieve peak performance, your heart and
lungs need oxygen-rich blood. When you
inhale tobacco smoke, you introduce carbon
monoxide into your system.
ā¢ This decrease in oxygen will reduce your
physical endurance, making it more difficult
for you not only to do well in sports but also
to do everyday things, such as walking up the
stairs or hillsides.
http://my.clevelandclinic.org/healthy_living/smoking/hic_smoking_and_physical_activity.aspx
45. Smokers and decline in fitness
ā¢ Decline in physical fitness and lung function
amonghealthy middle aged men was
considerably greater among smokersthan
among nonsmokers and could not be explained
by differencesin age and physical activity.
ā¢ Even initial fitness was substantially lower
among 347smokers than among 791 non-
smokers (1349 J/kg v 1618J/kg), as was initial
forced expiratory volume (3341 ml v 3638ml).

46. Learn to raise heavy things
ā¢ Bow your knees
and do the work
with your feet, not
with your back.
http://www2.edu.fi/materiaalipankki/index.php?id=74
47. ā¦ to work low in the right way
ā¢ Bow your knees
and stay down
when you work
with something
which is low.
http://www2.edu.fi/materiaalipankki/index.php?id=74
48. ... to work on the right height
ā¢ Try to arrange
that your working
table is on the
right height.
http://www2.edu.fi/materiaalipankki/index.php?id=74
49. Know your body
ā¢ In the human being there are more than 200
bones and 600 muscles. They make about 40
% of the weight of the man. How many of
them do you know by name?
Bones:
Ā· Skull
Ā· Clavicle
Ā· Ribs
Ā· Hip-bone
Ā· Thigh-bone
Ā· Shin-bone and tibia
Muscles:
Ā· Deltoid
Ā· Biceps femoris
Ā· Quadriceps femoris
Ā· Soleus
Ā· Tibialis anterior
Ā· Tibialis posterior
50. Train your body
ā¢ Training program can help you to get a better
condition.
ā¢ Choose a place where you can run 80 meters.
ā¢ Take time and also pulse.
ā¢ Write them daily on a paper and look how
your strength and oxygen transport capacity
grows when the training program continues.
51. Active life makes you
happier and healthier.
Do not distroy your health
with tobacco or drugs.
You can decide of your own life!.
