  system
  

• 2 слайд

  The cardiovascular system includes
  heart
  blood vessels
  lymphatic vessels
  

• 3 слайд

  The heart lies in the chest immediately behind the breastbone.
  

• 4 слайд

  The heart consists of two chambers, left and right, separated from each other by a wall.
  

• 5 слайд

  Each chamber is divided into upper compartment (atrium) and lower compartment (ventricle).
  

• 6 слайд

  Valves
  the tricuspid vaive –
  between the right atrium and the right ventricle
  the mitral valve –
  between the left atrium and the left ventricle
  semilunar valves –
  between ventricles and arteries
  RV
  LV
  RA
  LA
  aorta

  артерия
  

• 7 слайд

  To prevent blood flowing the wrong way.
  The function of the valves
  

• 8 слайд

  The circulation
  

• 9 слайд

  The heart works as a pump. It circulates blood throughout the body.
  

• 10 слайд

  The circulation occurs with the help
  of arteries and veins.
  

• 11 слайд

  Blood vessels
  Arteries
  vessels carrying blood away from the heart
  Veins
  vessels returning blood to the heart
  thin-walled vessels
  Capillaries

  Trasportation (the nutrients, oxygen are carried by the blood stream and cellular wastes are carried away by the blood stream).
  
  
  
  2. Regulation (supply the constant inner state and temperature of the body).
  
  
  
  3. Protection (provide the immunity and the blood clotting).
  Functions
  

• 16 слайд

  Blood is a liquid tissue containing plasma and microscopical cellular elements.
  PLASMA
  vessel
  Leucocytes
  Erythrocytes
  Thrombocytes
  (platelets)
  45%
  55%
  

• 17 слайд

  Erythrocytes
  Hemoglobin is an important protein
  which helps in carrying the oxygen and carrying away carbon dioxide.
  Erythrocytes are red blood cells made in the bone marrow. They are important in transporting oxygen.
  hemoglobin
  erythrocyte
  4.5 – 5 million in each cubic millimeter
  
  

• 18 слайд

  Leucocytes
  white blood cells
  From 4,000 to 10,000 per cubic millimeter
  8-10 mkm
  monocyte
  lymphocyte
  eosinophil
  basophil
  neutrophil
  leukopenia
  leukocytosis
  The cells of the immune system
  that are involved in protecting the body.
  

• 19 слайд

  Thrombocytes
  or platelets formed in the bone marrow
  These cells are necessary for blood clotting.
  400,000 per cubic millimeter
  2-5 mkm
