  1. 1Which of the following is incorrect?
    1. AT-reg is a type of CD4 effectors
    2. BCD8 are cytotoxic B-lymphocytes
    3. CCD5 are antigen specific B lymphocytes
    4. Dgamma beta cells are a type of antigen specific cell
  2. 2Nonspecific lymphatic cells are released as inactive cells. Macrophages begin as monocytes in blood and differentiate when they've invaded the tissues.
    1. AT/T
    2. BT/F
    3. CF/T
    4. DF/F
  3. 3The bone marrow is a primary lymphatic organ because most lymph cells originate here. The thymus, spleen, and lymph associated tissues are all secondary lymphatic organs because these are places where lymph cells meet pathogens.
    1. AT/T
    2. BT/F
    3. CF/T
    4. DF/F
  4. 4In the high endothelial venule, B-lymphocytes are in the paracortex. The T-lymphocytes are in the primary follicle.
    1. AT/T
    2. BT/F
    3. CF/T
    4. DF/F

    1. AT/T
    2. BT/F
    3. CF/T
    4. DF/F
  8. 8The red pulp of the spleen is colored because of its rich trabecular vascularization and recycling of RBC from circulation. The white pulp has a role in fighting systemic infections.
