| 3 Lymphocyte production | 1 Include the lymph nodes, the thymus and the spleen |
| 7 The lymphatic version of plasma | 2 NK cells policing for foreign, infected or cancerous cells is immunological ____________. |
| 8 The B in B Cell stands for this; 10-15% of lymphocytes are B cells | 4 T cells that inhibit T and B cell activity |
| 11 Blockage of lymphatic drainage in an area | 5 The T in T Cell stands for this; 80% of lymphocytes are T cells |
| 12 What a B cell will become to produce immunoglobins for humoral immunity | 6 A mass of lymphoid tissue whose size is variable to due lack of a fibrous capsule |
| 16 This largest lymph organ is divided into blood-filled red pulp and nodule-like white pulp | 9 Five of these guard the digestive system from assault at the pharynx |
| 19 Flow of lymph helps maintain volume and composition of plasma and this | 10 T cells that stimulate T and B cell activity |
| 21 An example of a substance using lymph to enter the blood, in this case originating at the digestive system | 13 These are made and stored in the lymphoid organs |
| 22 T cells that provide cell-mediated immunity | 14 The NK in NK Cell stands for this; 5-10% of lymphocytes are NK cells |
| 23 Lymph organ beneath the sternum where T-cells mature and thymosins are produced | 15 A lymphoid nodule near the connection of the small and large intestines |
| 24 Connects the peripheral tissues to the veins; also called a vessel | 17 Where lymphocytes actively divide in a lymphoid nodule |
| 25 Helper and suppressor T cells collectively | 18 Working with the right lymphatic duct, this feeds most of the lymph into the left internal jugular and subclavian veins |
| 20 Small ovoid lymph organs with fibrous capsules that filter anything with an antigen out of the lymph |
