Show Answers

The spleen is the primary organ for lymphocyte production in adults.Committed stem cells can develop into multiple types of cells.The reticuloendothelial system (RES) contributes to hematopoiesis.None of the above statements are true.

Explanation

The reticuloendothelial system (RES) plays a role in hematopoiesis by supporting the development and maturation of blood cells. While the spleen is involved in lymphocyte activity, it is not the main site of lymphopoiesis in adults. Additionally, committed stem cells are restricted to differentiating into a single cell lineage.
