Megan, by structure and function the spleen is like two organs--an immune one, the white pulp, consisting of periarterial lymphatic sheaths and germinal centers, and a phagocytic one, the red pulp, consisting of macrophages and granulocytes lining vascular spaces (the cords and sinusoids).The white pulp generates protective humoral antibodies. Production and maturation of B and T cells and plasma cells also occur in the white pulp, as in other lymphoid organs. The red pulp removes unwanted particulate matter (eg, bacteria, senescent blood elements). Hematopoiesis, another function of red pulp, normally occurs in the spleen only during fetal life.
I have no idea what the size of a spleen in an 8 year old is supposed to be, but 10.5 cm doesn’t sound like a problem.
The enlarged lymph node (and spleen) might be due to an infection and the body pains might also be due to an infection. The best would be to wait 3 months and see if everything doesn’t clear up by itself. Good luck.
