Epithelial cells are a normal finding in a pap smear; that's the stuff that is meant to be "smeared." White blood cells are a nonspecific indication of inflammation; to learn about possible reasons, you should discuss with your health care provider, who has information about other testing that was done.

Epithelial tissue is non vascular, meaning it has no blood supply it rests on connective tissue for nourishment.
whereas most tissue are vascular (contain blood vessels), epithelium is avascular, meaning it lacks blood vessels. epithelial cells receive their nutrients from capillaries in the underlying connective tissue. although blood vessels do not penetrate epithelial sheets, nerve endings do; that is, epithelium is innervated (supply organ with nerve).
I think that the bottom of epithelial cells is closest to blood vessels (if one were to look at a flat 2D image. Endothelial cells similarly would have the top of the cell closest to blood vessels.
