What is the role of epithelial cells?
They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.
Where are epithelial cells?
Epithelial cells are a type of cell that lines the surfaces of your body. They are found on your skin, blood vessels, urinary tract, and organs.
What do epithelial tissues lack?
epithelium: A membranous tissue composed of one or more layers of cells that form the covering of most internal and external surfaces of the body and its organs. avascular: Lacking blood vessels.
What is the normal range of epithelial cells?
However, this is only if the number of epithelial cells is within a certain limit, as large amounts will warrant an additional look under a microscope. Typical diagnostic ranges fall into either few, moderate, or many, but can also be measured in number. A normal range is less than 15–20 per high power field (HPF).
What are the types of epithelial cells?
These epithelial tissues are in turn made up of different types of epithelial cells. There are three major kinds of epithelial cells associated with urinary tract. These three types of cells include transitional epithelial cells, squamous epithelial cell, and renal tubular cells.
What are epithelial cells specialized to do?
These cells line the intestines and are responsible for absorbing nutrients from digested food. Columnar epithelial cells in these cases often have multiple finger-like projections, which increase the surface area of the cells. A large surface area is necessary to maximize the efficiency of the absorption of these specialized cells.
What is the cause of increase in epithelial cell count?
