What is the singular form of Epithelium?
Epithelium is the singular form; the plural forms are epitheliums or epithelia, both are accepted.
What is epithelia with more than one layer?
The term for epithelium with more than one layer is stratified epithelium.
Does epithelium consists of closely packed cells?
Yes it does except for glandular epithelia.
What is the basis of biologist to classify a specific epithelial tissue?
Epithelia are tissues consisting of closely apposed cells without intervening intercellular substances. Epithelia are avascular, but all epithelia "grow" on an underlying layer of vascular connective tissue. The connective tissue and the epithelium are separated by a basement membrane. Epithelium covers all free surfaces of the body. Epithelium also lines the large internal body cavities, where it is termed mesothelium.
What type of simple epithelium is less easily categorized because of the variation in cells?
stratified epithelia
How does transitional epithelium structure differ from stratified squamous epithelia?
Transitional epithelium contains cells that are flattened and cells that are cuboidal; hence the name "transitional". Stratified squamous is different from transitional epithelium since the shape of the individual cell is more hexagonal and contains flattened cells. Transitional epithelium have the capacity to stretch and flatten.

What type of tissue covers the oral cavity?
its the epithelia Unkeratinised stratified squamous epithelium, to be exact.
What type of epithelium lines most of the respiratory tract?
The cells that line the epithelium in the tracheae are ciliated pseudostratified columnar epithelium cells.They are of three types -ciliated cellsgoblet cellsbasal cells
Which epithelium forms wall of air sacs of lungs?
simple squamous epithelium
What type of epithelial cell often had cilia?
Epithelia cells are the first cell type that differentiate in the embryo during the 8 cell stage. Epithelia are tissues that are formed by epithelial cells. These specialized cells are differ from others by the nature of avascular, sensory, gliding surface layer, tight barrier and differs from endothelial cells. They form the major cavities of the body. These cells form lungs, kidney, kidney, pancreas and so on. Epithelia act as sensory receptors, hence they form taste buds, nose, ear, female reproductive organs and so on.
What is it about the epithelium nature of cells that keeps oxygen from diffusing into our bodies through the skin?
The cells in the skin epithelium are cuboid, mostly dead, with very low vascularity and saturated with keratin which prevents not only gases from diffusing in and out of the body, but also prevents liquids and solutes from moving out of the body. There are, anyway, epithelia that allow oxygen flow, like the lung's epithelium, since epithelium is a kind of tissue that covers others, therefore, not only skin is epithelium.
