CARDIOVASCULAR SYSTEM

            • Heart

COMPOSED    • Blood vessels
            • Blood
  OF:

            • Supplying oxygen and
              nutrients to tissues and to
              remove wastes from tissues.
 Function   • Human circulatory system is
              double circulatory system.
Presentation anatomy
PULMANORY CIRCULATION
The pulmonary circulatory system
carries poorly oxygenated and
waste-containing blood from the
right ventricle (the lower right
chamber) of the heart to the lungs.
   where the waste products are filtered
   into the lungs to be exhaled, and
   oxygen is filtered from the lungs into
   the blood, to be carried
   back, oxygen-rich by the pulmonary
   circulatory system to the left atrium.
              The left atrium is the upper left
              chamber of the heart. It passes the
              oxygen-rich blood from the
              pulmonary circulatory system
              through the pulmonary artery to
              the systemic circulatory system
              through the left ventricle.
SYSTEMIC CIRCULATION
    The left ventricle pumps oxygenated blood into the
   aorta, and from there the systemic circulatory system
carries this oxygen-rich blood to the rest of the body via the
         arteries and capillaries into tissues and cells.


     The veins of the systemic circulatory system carry
   deoxygenated blood and blood containing waste
products away from the cells and tissues back to the right
atrium (the upper right chamber of the heart) where the
         blood is pumped into the right ventricle.



The blood is then passed back to the pulmonary circulatory
           system where the cycle begins again
IMAGE OF PULMANORY AND SYSTEMIC CIRCULATION
BASIC ANATOMY OF THE HEART
• heart is located between your lungs in the middle of your chest
              • behind and slightly to the left of your breastbone (sternum).
LOCATION



              • The heart weighs between 7 and 15 ounces (200 to 425 grams).
              • Cone shaped.
              • Man’s fist
WEIGHT/SIZE   • The average adult heart is 14cm long and 9cm wide.




              • Epicardium –covers the outer surface of the heart.
              • Myocardium –contains cardiac muscle tissues
              • Endocardium-inner surface of the heart
HEART WALL
    Two upper chambers
   Right atrium
   Left atrium

ATRIUM have THINNER compared to the
         ventricles.Because it just to pump
          blood to the ventricles.


   Two lower chambers
   Right ventricles
   Left ventricles

LEFT VENTRICLES has a much THICKER WALL than the right
   ventricles.Because right ventricles only pumps blood to the lung but The
   left ventricle has to pump blood to the rest of the body.
VALVES –Prevent backflow of blood
   Tricuspid valve
   Bicuspid valve
   Semilunary valve (Aortic and Systemic)
   Deoxygenated blood enters right atrium through superior and inferior
    vena cava.

   Right atrium contract and open tricuspid valve to enter right ventricle.

   From right ventricle, the blood goes through semilunar valve and enters
    pulmanory artery and be send to lung.

   CO2 diffuses out, O2 diffuse in - diffusion.

   After exchange of gases occurred, the blood carried back to heart
    through pulmanory vein then to the left atrium.

   Left atrium contract and opens bicuspid valve to enter left ventricle.

   From left ventricle oxygenated blood will flow through semilunar valve
    and send to ascending aorta and descending aorta to all parts of body.

EXAMPLES OF DISEASE

   Arrhythmia
    The major symptom of cardiac arrhythmia is irregular
    heart rhythm, in which the heart beats abnormally,
    either at a slower rate or faster rate.

   Angina
    Angina, characterized by severe and recurrent chest
    discomfort and pain, is caused due to lack of blood
    supply and or oxygen supply in the muscles of the
    heart.

   Atherosclerosis
    Atherosclerosis is a blood circulation problem,
    resulting from accumulation of fatty deposits in the
    walls of the blood vessels, especially arteries.

   Hypertension/high blood pressure
    systolic pressure more than 140mm hg and diastolic
    pressure more than 90mm hg.

 YOU!!!
