    left side - systemic circuit
  11. what are the three blood vessels?
    arteries , veins and capillaries
  12. arteries take the blood from
    <3 to body
  13. veins take blood from
    body to <3
  14. capillaries...
    transfer blood b/w veins and arteries
  15. pathway of the blood..
    superior/inferior vena cava - right atrium - tricuspid valve - right ventricle - pulmonary artery - lungs - pulmonary vein - left atrium - bicuspid valve - left ventricle - aorta - body
  16. What is blood?
    A complex, living tissue that contains many cell types and proteins
  17. What are the two functions of blood?
    • 1) pick up and deliver nutrients
    • 2)take away waste
  18. What are the four delivery jobs?
    • 1) delivers nutrients from fats, proteins and carbohydrates to all body cells
    • 2) delivers oxygen to all body cells
    • 3) delivers chemical messengers to some body cells
    • 4) delivers water, minerals and vitamins to all body cells
  19. What are the three pick up jobs?
    • 1) pick up carbon dioxide waste from all cells and carry to lungs
    • 2) pick up chemical waste from cells and carry to the kidneys
    • 3) pick up body heat and carry to the skin (red flush from excercise)
  20. what are examples of animals with NO blood
    sponges, jellyfish and flatworms
  21. What are the two important components of blood?
    • 1) Plasma - nonliving yellow liquid (92%water, 8% proteins,nutrients and salt)
    • 2) Bone Marrow - the soft center of the bone (makes red and white blood cells)
  22. Red blood cells ...
    • - carry oxygen
    • - 5 million in one drop of blood
    • - live 120 days
    • - no nucleus
    • - make up the majority of your blood
  23. Hemoglobin is..
    a protein in red blood cells that joins with oxygen and gives the red cells their color ; contains IRON
  24. Anemia is..
    a condition in which there are too few red blood cells in the blood (person feels week, tried and short of breath)
  25. White blood cells ...
    • - destroy harmful microbes
    • - remove dead cells
    • - make proteins that help prevent disease
    • - have nucleus
    • - bigger than red blood cells
    • - 8000 in one drop of blood
    • - live ten days
    • - made in the spleen, thymus and tonsils
  26. Leukemia is..
    a blood cancer in which the number of white blood cells increases at an abnormal rate
  27. Platelets ...
    • - aid in forming blood clots
    • - not complete cells
    • - smaller than red blood cells
    • - 250,000 in a drop of blood
    • - live 5 days
  28. Hemophilia is..
    a Genetic disease in which a persons blood wont clot
  29. What are the four main types of blood types
    A , AB , B, O
  30. What is the difference in the type of blood?
    Difference is due to proteins found in red blood cells and in blood plasma
  31. Type A and B blood cells are ..
    different ; type A has antigens A and anti - B antibodies. type B has antigens B and anti - A antibodies
  32. Type AB red blood cells ..
    are the same as both A and B , has no plasma proteins ; has antigens A and B and neither antibodies
  33. Type O ...
    has plasma protein like A & B ; has neither A or B antigens but has both antibodies
