Epithelial tissue performs a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion and sensory reception. D. Where is connective tissue found in the body? Under a microscope, epithelial cells are readily distinguished by the following features: The epithelial layer on one side will face an empty space (or, in some organs, it will face a secreted substance like mucus) and on the other side will usually be attached to connective tissue proper.
