Verified step by step guidance

Understand the role of the lymphatic system in the body, which includes the production and maturation of immune cells, and in some cases, the production of erythrocytes (red blood cells) during fetal development.

Identify the primary lymphatic structures: spleen, thymus, lymph nodes, and bone marrow, and understand their functions in both adults and fetuses.

Recognize that the spleen is a lymphatic organ that, in addition to filtering blood and housing immune cells, can also produce erythrocytes during fetal development.

Consider the role of the liver and bone marrow in erythrocyte production. The liver is involved in erythrocyte production during early fetal development, while bone marrow takes over this role after birth.

Conclude that the spleen is the lymphatic structure that may also be a site of erythrocyte production in the fetus, as it has the capability to produce red blood cells during this stage of development.
