    Transcript

    00:01 In order to respond to an infection, lymphocytes need to become activated.

    00:06 So we’re going to look at lymphocyte activation.

    00:09 The lymphoid tissues can be divided into primary lymphoid tissues where the lymphocytes develop and secondary lymphoid tissues where they become activated.

    00:20 Hematopoietic stem cells in the bone marrow give rise to the B-lymphocytes within the bone marrow itself, whereas those cells that are going to become T-lymphocytes travel to the thymus.

    00:36 The B-lymphocytes and T-lymphocytes leave the primary lymphoid tissues once they reach maturity and travel to the secondary lymphoid tissues which are the lymph nodes, the spleen and the mucosa-associated lymphoid tissue or MALT.
