In the normal animal immune complexes (lattice of soluble antigen and antibodies) are formed and removed all the time. They are broken up by complement, transported to the spleen by RBC's and phagocytosed. When the amount of immune complexes formed (due to rapid influx of antigen) does not equal the amount that are being cleared it causes type III hypersensitivity (an excess of immune complexes).
