GENERAL HISTOLOGY

Detailed explanation-1: -RBCs pass through both the spleen and liver, where specialised immune cells called macrophages are found. Macrophages recognise when an RBC is spent, and undergo a process called phagocytosis where they digest the cell.

Detailed explanation-2: -Your spleen is involved in your body’s immune response, and in recycling old blood cells.

Detailed explanation-3: -The embryonal spleen derives from primitive mesenchyme. During the fifth fetal month certain fixed mesenchymal cells in the spleen give rise to so-called hemocytoblasts which in turn produce erythroblasts. 9 At this time the production of red cells is a normal function of the spleen.
