Final answer:
The lymphocytes of the outer cortex in lymph nodes are mainly arranged in germinal centers with B cell-rich and T cell-rich areas.
Step-by-step explanation:
The lymphocytes of the outer cortex in lymph nodes are mainly arranged in germinal centers of rapidly dividing B cells surrounded by a layer of T cells and other accessory cells.
For example, lymph nodes contain specialized macrophages and dendritic cells that are crucial for antigen presentation to T and B lymphocytes. These lymphocytes play a crucial role in the immune response, as they are responsible for recognizing and attacking foreign pathogens in the body.
Overall, the lymphocytes in the outer cortex of lymph nodes are organized in germinal centers with specific B cell-rich and T cell-rich areas, allowing for efficient immune responses.
