Where else on the human body can we find epithelial cells?

Question

Hi everyone,

I want to ask where else on the human body can we find epithelial cells other than the cheek cells?

Thanks!

Answer 1

In dermatology, epithelium is a tissue composed of a layer of cells. In humans, it is one of four primary body tissues. Epithelium lines both the outside (skin) and the inside cavities and lumen of bodies. The outermost layer of our skin is composed of dead stratified squamous epithelial cells, as are the mucous membranes lining the inside of mouths and body cavities. Other epithelial cells line the insides of the lungs, the gastrointestinal tract, the reproductive and urinary tracts, and make up the exocrine and endocrine glands.

Functions of epithelial cells include secretion, absorption, protection, trans-cellular transport, sensation detection, and selective permeability. Endothelium (the inner lining of blood vessels) is a specialized form of epithelium.

Everywhere!!

"Epithelial tissues cover or line all body parts both externally and internally. "

It is just easier to do a cheek swab, where they are more loosely attached, than to cut skin off! OUCH!!
