What is primary lymphoid tissue?
Where stem cells differentiate into either T cells (thymus) or B cells (bone marrow).
What is secondary lymphoid tissue?
Where mature T/B cells go to encounter antigens.
Where is secondary lymphoid tissue in the body?
MALT (mucosal-associated lymphoid tissue) and other locations in the body with excess lymphatic accumulations
What three activities take place in the thymus?

2. Self/non-self discrimination
3. Elimination of self-reacting thymocytes
