1
Q
Function of Residual bodies
A
the intracellular accumulation of residual bodies is related to the cell’s capacity to cope with potentially threatening bacteria or to deal with damaged organelles
2

Q
How do residuals bodies come into existence?
A
When the tissue is destroyed the cell’s attempt to survive relies on a lysosome to engulf the damaged portion and break it down as much as possible, these lysosomes spit up fragments that can not be ingested and remain as separate isolated bodies in the cell known as residual bodies
