					Circulatory
  System

   By: Audrey
Each breath you take brings air into your
lungs. That air is needed by the trillions of
cells in your body. Your heart is essential
in delivering that oxygen. It’s beating
produces the force to move oxygen rich
blood threw the circulatory system.
             Function

• Brings oxygen, nutrients, and
  hormones to cells.
• Fights infections
• Regulates body temperatures
             Structures

• Heart

• Arteries

• Veins
Heart
                  Arteries
• Arteries carry mostly
  oxygenated blood
  away from the heart
  to the tissue and
  organs in the body
                 Veins
• The Veins are
  responsible for the
  transportation of
  deoxygenated blood
  back to the heart.
                 Diseases

• High blood pressure

• Heart attack

• Stroke
               High Blood
                Pressure

• Forces the heart to
  work harder, which
  may weaken or
  damage the heart
  mussels and blood
  vessels.
Heart Attack
      • Coronary arteries, a
        set of arteries that
        bring oxygen and
        nutrients to the heart.
        If one of these
        arteries becomes
        blocked, part of the
        heart may begin to
        die due to lack of
        oxygen.
                 Stroke
• Blood clots break
  free and gets stuck
  in one of the blood
  vessels leading to
  the brain.
              Blood Types
• If two different blood types are mixed together,
  the blood cells may begin to clump together in
  the blood vessels, causing a potentially fatal
  situation. Therefore, it is important that blood
  types be matched before blood transfusions take
  place. In an emergency, type O blood can be
  given because it is most likely to be accepted by
  all blood types.
              Donating Blood
• A person with type A
  blood can donate blood to
  a person with type A or
  type AB. A person with
  type B blood can donate
  blood to a person with
  type B or type AB. A
  person with type AB
  blood can donate blood to
  a person with type AB
  only. A person with type
  O blood can donate to
  anyone.
         Receiving Blood
• A person with type A blood can receive
  blood from a person with type A or type
  O. A person with type B blood can
  receive blood from a person with type
  B or type O. A person with type AB
  blood can receive blood from anyone.
  A person with type O blood can receive
  blood from a person with type O.
