lymphatic system/immunity

• T/F: calcium homeostasis is a function of the lymphatic system

  false
• T/F: the pancreas is part of the lymphatic system

  false
• a difference between the lymphatic and cardiovascular capillaries is

  blind ends
• the largest driving force for moving fluid from the capillaries into the interstitial spaces is

  Hydrostatic pressure
• T/F: the spleen removes old blood cells


  true
• where do immune cells mature

  primary lymphatic organs, they are produced in the bone marrow but mature in primary lymph organs
• lymphatic vessels differ from cardiovascular vessels because they

  have larger pores and one way pores
• secondary lymph organs

  mount immune responses
• the lymphatic system is important to pathogen defense because


  its pores allow microorganisms to be brought in from the tissue
• lymph drain into the

  subclavian veins
• declines in size/usage as you get older and become an adult

  thymus
• the thymus is most pronounced in


  infants
• where do T cells mature

  thymus, mediastinum
• what is comprised of red and white pulp

  spleen
• non specific internal diseases resisting mechanism

  macrophages
• which white blood cell is an abundant phagocyte

  neutrophil
• interferon

  reduce viral replication
• the self antigens are known as ___ and are not attacked by a healthy immune system because

  MHCs; immune cells that attack them don't mature
• complement system

  promotes cytolysis, phagocytosis, inflammation
• which cells kill infected body cells and tumor cells

  natural killer cells
• T/F: mucus production is a sign of inflammation

  false
• cytotoxic T cells kill infected cells when the ___ binds to their ___

  MHC I; CD8
• when B and T cells are fully developed and mature, they are described as

  immunocompetent
• which class includes macrophages and dendritic cells

  antigen presenting cells (APCs)
• what cells have CD4 and interact with MHC II antigens

  helper T cells
• opsonization


  makes microbes more susceptible to phagocytosis
• natural exposure to an infectious agent leads to

  active immunity
• this type of immunity will defend against any type of invader

  non specific
• each individual mature B cell produces antibodies against ___ antigens

  non self, one specific, randomly selected
• what type of immunity will result from immunoglobulins being injected

  artificial passive, immunoglobulins are antibodies
• what type of adaptive immunity is going to result from a mother to baby IGa transfer

  natural passive
• the spleen has the function of

  removing damaged rbc
• the characteristics of inflammation (redness, swelling, warmth, pain) are most directly due to

  blood plasma leaking from the capillaries
• the lymphatic system is important to pathogen defense because


  its pores allow microorganisms to be brought in from the tissues
• cytotoxic T cells kill infected cells when the ___ binds to their ___

  MHC I; CD8
• each individual matures B cell produces antibodies against ___ antigen(s)

  one specific and non self and randomly selected
• the self antigens are known as ___ and are not attacked by a healthy immune system because

  MHCs: immune cells that attack them don't mature
