  1. What does the Cardiovascular System do?
    Uses blood to carry material to/from cell
  2. What are the Veins?
    Blood vessels that direct blood back to the heart.
  3. What are Arteries?
    Blood vessels that direct blood away from the heart.
  4. What is Hemoglobin?
    The protein that gives the RBC's their color, sticks to inhaled oxygen.
  5. What does blood compose of?What is it?
    Connective tissue, Composed of Plasma, Blood Cells,Platelets
  6. What are Antibodies?
    A protein released by WBC to destroy pathogens.
  7. What is plasma?
    The fluid part of the blood.
  8. What are RBC? What does it do?
    Most blood cells are RBC. To take oxygen to the cells.
  9. What are WBC?
    Cells that help people stay healthy by destroying pathogens.
  10. What are Capillaries?
    They are the smallest blood vessel, so small, blood cells must pass through single file.
  11. What is an atria?
    Upper chamber of the heart
  12. Whats a ventricle?
    Lower chamber of the heart.
  13. Lymphatic System?
    Collection of organs that return extra fluid.
  14. Lymph
    Fluid and particles absorbed into the lymph capillaries
  15. Lymph Nodes
    Small, bean-shaped organs that remove pathogens.
  16. Spleen
    Largest lymph organ. Filters blood
  17. Lungs
    Spongelike, contains alveoli.
  18. Diaphragm
    Dome-Shaped muscle, that,when contracting, increases the chest cavity
  19. Bronchi
    2 tubes the trachea splits up into.
  20. Alveoli
    Thousands of tiny sacs in the lungs
  21. Pharynx
    Throat. Air, Food, Drink travels through. branches into 2 tubes. Esophagus->to the stomach. Larynx->To the lung
  22. Thrachea
    Windpipe. Passageway for air trveling from larynx to the lung
  23. Digestion
    Process of breaking down food
  24. Saliva
    Made in salivary gland, has enzymes that begin chemical digestion.
  25. Chemical and Physical Digestion
    • Large molecules being broken down.
    • Physical crushing and breaking of food.
  26. Esophagus
    A Tube that leads from thrachea to the stomach.
  27. Large Intestine
    Organ in the digestive system that stores compacts and gets rid of indigestible waste.
  28. Villi
    Small finger like projections that increase the surface area of the Small Intestine
  29. Chyme
    The digested mixture in the stomach
  30. Enzymes
    A substance that breaks down nutrients
  31. Pancreatic juices
    A juice in the pancreas that has enzymes
  32. Functions of liver
    • Makes bile
    • Stores nutrients
    • Breaks down toxic material
    • Makes cholesterol
  33. Bile
    Something made and used in fat digestion. Stored in the gallbladder. Green
  34. Small Intestine
    Where chemical digestion takes place. Covered in Villi
  35. Urinary System
    Removing of waste products from blood
  36. Methods of extretion
    Integumentary, respiratory,urinary systems
  37. Kidneys
    Pair of bean-shaped organs, clean the blood
  38. Nephron
    Tiny filterers in the kidneys
  39. Urea
    Contains nitrogen, forms when cells use proteins
  40. Ureter
    Small tube in which the urine leaves the kidneys.
  41. Bladder
    Where urine is stored
  42. Urethra
    Where the urine leaves the body
  43. Diuretic, Example
    Makes more urine, Caffeinated drinks
  44. ADH
    Hormone that signals kidneys to take back water
