Question

Which statement is TRUE about lymphatic cells and lymphatic tissue? B lymphocytes act as antigen-presenting cells to activate naïve T cells. Lymphoid macrophages respond to antigens by secreting antibodies into the blood. Once an immunocompetent lymphocyte enters lymphatic tissue, it resides there permanently. Every immunocompetent T cell and B cell responds to a specific antigen, which is why self-tolerance is important in their maturation.

Step 1

Statement A: B lymphocytes act as antigen-presenting cells to activate naïve T cells. - This statement is incorrect. B lymphocytes are not antigen-presenting cells; instead, they are responsible for producing antibodies. Antigen-presenting cells, such as Show more…
