Verified step by step guidance

Begin by understanding the role of T cells and B cells in the immune system. T cells are primarily involved in cell-mediated immunity, while B cells are responsible for humoral immunity, producing antibodies.

Recognize that both T cells and B cells originate from hematopoietic stem cells, which are found in the bone marrow. This is the primary site for the production of all blood cells, including immune cells.

Identify the maturation process of these cells: B cells mature in the bone marrow itself, whereas T cells migrate to the thymus to complete their maturation.

Consider the options provided: Bone marrow is the site of production for both T cells and B cells. The thymus is specifically involved in the maturation of T cells, not their production. The bloodstream is where these cells circulate after maturation, and epithelial cells are not involved in the production of T or B cells.

Conclude that the correct answer for the production site of both T cells and B cells is the bone marrow, as it is the origin of hematopoietic stem cells that differentiate into these immune cells.
