Which of the following types of cells can be found in lymph nodes?

Lymph nodes are critical components of the lymphatic system and play a key role in immune response. They are structured to house various immune cells that contribute to identifying and neutralizing pathogens.

B lymphocytes, also known as B cells, are responsible for producing antibodies against specific antigens. They are essential for the humoral immune response and can be activated within lymph nodes when they encounter their specific antigen.

Macrophages are large phagocytic cells that are crucial for innate immunity. They help in engulfing and digesting pathogens and also in presenting antigens to T cells, thereby enhancing the adaptive immune response. These cells are plentiful in lymph nodes, where they play a pivotal role in filtering lymph fluid and maintaining immune surveillance.

T lymphocytes, or T cells, are another vital component of the immune system found in lymph nodes. They are central to cell-mediated immunity and can be divided into various subtypes, including helper T cells and cytotoxic T cells. Like B cells, T cells are activated by antigens displayed on the surface of dendritic cells and macrophages in lymph nodes.

Given that all these types of cells—B lymphocytes, macrophages, and T lymphocytes—are integral to the function of lymph nodes, the
