  1. List 3 functions of the lymphatic system.
    • 1. Produce, maintain and distribute lymphocytes.
    • 2.Maintain normal blood volume 
    • 3. Transport dietary lipids
  2. The lymphatic network is not a circuit. Where does it begin and with what vessels?
    In cardiovascular capillary networks 

    Lymphatic capillaries
  3. There really isn't any pressure in lymphatic vessels, so like veins they have _____.
  4. Match the two major lymphatic vessels to their drainage areas. 

    lower body and left upper body-
    Thoracic duct
  5. Match the two major lymphatic vessels to their drainage areas.

    Right upper body (above diaphragm)-
    Right lymphatic duct
  6. Where do they drain lymph back into our cardiovascular system?
    Junction of subclavian and internal jugular veins
  7. What lymphatic organ is the site of maturation and differentiation for t-lymphocytes?
  8. Where is it located?
    Deep to the sternum

    Overhanging the vessels above the heart
  9. What lymphatic organ is the site of maturation for b-lymphocytes and NK cells?
    Red bone marrow
  10. Where is red bone marrow located?
    Proximal epiphyses of long bones

    some flat bones
  11. What is red bone marrows general function other than contributing to immunity (technical term)?

  12. Match the specific tonsils to their description. 

    single, located in superior nasopharynx
    Pharyngeal tonsil
  13. Match the specific tonsils to their description.

    Paired, located on each side of the posterior oral cavity
    Palatine tonsils
  14. Match the specific tonsils to their description. 

    Paired, located on the base of the tongue
    Lingual tonsils
  15. What lymphatic organs are small, oval organs up to 1 inch in diameter filter lymph and house macrophages and lymphocytes, and in what 3 regions are they most noticeable?
    Lymph nodes

    Cervical, axillary, inguinal
  16. Because lymphatic vessels are highly permeable and because lymph nodes are maze-like to trap pathogens moving through the lymph they tend to trap cancer cells that break free from a primary tumor. What term do we use to refer to this cancer-related phenomenon that may require the removal of lymph nodes downstream from a tumor?
  17. What lymphatic organ (largest) lies in far upper left of the abdomen and removes old/abnormal blood cells (they rupture as tehy move through capillary walls into sinus and are phagocytized by macrophages), stores iron, and initiates an immune response to antigens found in the blood?
