Primary lymphoid tissue 39 Stores blood placelesand reyles eybytes 40. Drains lymph from most of the body and retarns it to the left subelavian vein. 41. Filters lymph received through lymph vessels 42. Isolated clusters of lymph follicles found in the wall of the small istestime. 43. Which of the following is found in the spleen? a red pulyp b. white pulp c. macrophages e. all of the above 44. Which of the following is a function of a lymph node? a. produce antibodies b. produce lymphocytes c. remove pathogens d. capture foreign antigens e all of the above edema associated with inflammation is directly caused by a. the large number of platelets b. blockage of veins by plasma proteins 45. The attracted to the area of capil release of antibodies by activated T cells e, antigen-antibody complexes d. Which of the following is true regarding lymphatic capillaries? a. have valves in their walls b. allow fluid to enter, not exit c are loca d. collect excess interstitial uid e all of the above ted near systemic capillariesExplanation / Answer
38. [ primary lymphoid tissue are where lymphocytes are formed and matured]: Thymus Gland,(another one is red bone marrow)
39: Spleen [ it the organ which filters out normal RBC and platelets to blood, and destroys deformed blood cells].
40. Thoracic duct
41. Lymph Nodes [ as you know lymph vessels drains into lymph node where lymph is filtered to sort out infective agents for destruction ].
42. MALT [ Full form: Mucosa-Associated Lymphoid Tissue ]
43. All of the above [ spleen is tissue which filters blood cells and platelet, and its structure are red pulp ( formed by connective tissue ie blood ) and white pulp ( composed of lymphocytes) ]
44. d. captures foreign antigens [ lymph nodes capture foreign antigens and present them to lymphocytes, an antibody is produced by lymphocytes, not lymph nodes, Antigens are removed by phagocytes, not by lymph nodes, lymphocytes are produced by thymus gland and red bone marrow ]
45.c increased permeability of capillaries.
46. All of the above [ lymphatic capillaries are vessels located in the spaces between cells. They do have valves and only allow interstitial fluid to enter not out. These lymphatic vessels drain into blood capillaries so they are located near blood capillaries ]
