    Circulatory system( science) Circulatory system( science) Presentation Transcript

    • Circulatory System
      Circulation
      Heart structure
    • Circulation
    • Function:
      • To transport materials
      around the body
      • Oxygen
      • Carbon dioxide
      • Digested food
      • Hormones
      • Waste chemicals - urea
      Heat
    • 3 Major Parts of the Circulatory system
      • Blood Vessels- routes blood travels
      • Heart– pumps or pushes blood through body
      • Blood– carries important “ *stuff ” through body
      * Stuff – includes oxygen, food, & waste
    • 1 Blood Vessels: One Way Streets
      • Blood Vesselsresemble very long and skinny tunnels that are all through your body.
      • #2 The Heart
      4 chambers ( or compartments )
      2 upper chambers : Left Atrium Right Atrium
      2 lower chambers : Left Ventricle
      Right Ventricle
      • #2 The Heart
      4 chambers ( or compartments )
      2 upper chambers : Left Atrium Right Atrium
      2 lower chambers : Left Ventricle
      Right Ventricle
    • Lub
      Dub
      If you listen to your heartbeat, it makes a lub dub sound.
      The lub is when blood is pushed out of the heart into the body and the dub is the reloading of the heart with more blood ready to push it out to the body
    • Double Circulation
      Left side
      Oxygenated blood from the lungs enters the heart and is pumped to the body organs and tissues
      Right side
      Deoxygenated blood from the body is returned to the heart to be pumped to the lungs
    • Blood Flow through the Human Body
      Blood with little oxygen is pumped from the Right Atrium through a valve to the Right Ventricle and through another valve into the Pulmonary Vein. The Pulmonary Vein sends it to the Lungs to pick up Oxygen. It’s sent from the Lungs through Pulmonary Arteries to the Left Atrium through a valve to the Left Ventricle. The Left Ventricle sends it through a valve to the Aorta. The Aorta is a series of branches that sends oxygenated blood throughout the body.
    • Pulmonary system – up to the lungs
      CARBON DIOXIDE
      OXYGEN
      Systemic – to the organs of the body
      • Heart Rate can be determined using a Stethoscope
    • Your Blood is made of
      • Plasma
      • Liquid part of blood
      • Red Blood Cells
      They carry oxygen to all parts of the body
      • White Blood Cells
      • Fight and kill germs that may enter your bloodstream
      • Platelets
      • Form “scabs” when you cut yourself
      • Helps stop the bleeding
    • BLOOD TYPE
      The ABO blood groups are the features most people know about.
      In this group, there are 4 different types of red blood cells -- A, B, AB, and O.
    • If someone is in an accident, has surgery or gets cancer, they may need another person’s blood to help them survive.
      There is no substitute for blood transfusion.
      This blood comes from blood donors.
    • It is quick and it is safe.
      It doesn’t hurt badly at all.
      And it saves lives.
      DONATING BLOOD
    • BLOOD FACT
      About half of world population who are above 18 years can safely be blood donors.
      But only about 5 percent actually donate blood.
      The other 95% are relying on these donors if they ever need a transfusion.
    • EVALUATION
      FILL IN THE BLANKS
      In mammals, the ……………………………. Is divided into four parts.
      The heart …………………………. Continuously .
      The vessels carrying blood from the heart to the different parts of the body are called …………………………………………
      The vessels carrying blood from the parts of the body to the heart are called ………………………………….
    • FILL IN THE RIGHT WORDS USING THE CLUES.
      1)BLOOD
      Route bloods travels
      and
      Voice maid by heart
      3)
      Pumps or pushes blood through body
      GIVE REASONS
      The walls of capillaries are thin.
      2) It is necessary to match blood groups before giving a transfusion.
