Problem 1: Compare and contrast the morphology of the tissue sections of infant thymus and a lymph node. Describe 2 ways that they are similar in structure and 2 ways that they are different in structure?
Problem 2: Compare and contrast the morphology of the spleen and a lymph node. (i) Describe 2 ways that they are similar in structure and 2 ways that they are different in structure? (ii-1) Where do antigen presenting cells enter the lymph node and where do they enter the spleen? (ii-2) What do these differences in structure suggest about the primary source of antigens for the spleen versus lymph nodes?
Problem 3: Compare and contrast the morphology of the adult and infant thymus. (i) Describe I way that they are similar in structure and I way that they are different in structure? (ii) What do these differences signify about the role of the thymus in T cell development in infants versus adults?
Problem 4: Compare and contrast the morphology of the tissue slides of tonsils and the infant thymus. (i) Describe 2 ways that they are similar in structure and 2 ways that they are different in structure? (ii) On what morphological feature would you determine that tonsils are secondary lymphoid organs?
