No, simple epithelia are typically found in areas of minimal wear and tear as they provide limited protection. In areas of high abrasion, stratified epithelia are more common as they offer multiple layers of cells for durability and protection.
Simple cuboidal epithelia are found in areas of the body where secretion and absorption processes occur, such as in the kidney tubules, thyroid gland, and small ducts of various glands. They are characterized by a single layer of cube-shaped cells with a centrally located nucleus, which facilitates their specialized functions of secretion and absorption.
Goblet cells are the cells in both simple columnar and pseudostratified columnar epithelia that produce protective mucous coatings over mucous membranes. These cells secrete mucus, which helps to lubricate and protect the surface of the tissues from damage, dehydration, and invasion by pathogens.
Microvilli cells are simple columnar epithelium. Stratified epithelia don't have cilia or microvilli because they are on the inner layers of epithelia. Think about it, cillia and microvilli are used to help the processes of absorption and secretion within the lumen. ex: upper respiratory tract.

Simple columnar
Paracellular transport systems move substances across simple epithelia by passing between adjacent cells through tight junctions, while transcellular transport systems move substances across simple epithelia by passing through the cytoplasm of the epithelial cells.

Simple receptors found in epithelia and connective tissue tend to detect physical stimuli such as pressure, touch, and temperature changes. They send sensory information to the brain via sensory neurons to help in the perception of the external environment.

Transitional epithelia serve as a protective barrier and allow for stretching in organs like the bladder and ureters in the human body.
