Cellular function varies.  Certainly squamous epithelial cells are "dead cells", that are eventually just sloughed into the environment, replaced by new "dead cells".

Your body has macrophages (http://en.wikipedia.org/wiki/Macrophage) that are essentially the cellular garbage men.  They can move through tissues to the site where they need to remove debris including dead cells.

Lysosomes (http://en.wikipedia.org/wiki/Lysosome) are an intracellular component in all animal cells (including macrophages) that are involved with recycling cellular components, and even digestion of foreign bodies within the cells.  There are a number of metabolic disorders related to defects with the Lysosomes (http://en.wikipedia.org/wiki/Lysosomal_storage_diseases).

And then there's the internal lining of your Gastrointestinal tract. Dead cells of the GI-tract cell walls make out part of your poo :)
