Secretion
They are modifications of simple columnar epithelial tissue.
Epithelial tissue exhibits polarity, with distinct apical and basal surfaces. This polarity allows epithelial cells to carry out specialized functions such as absorption, secretion, and barrier formation.
Connective tissue is not lined with epithelial cells.
epithelial cells of the semiinferous tubules.
The cheek epithelial cells are flat and irregularly shaped. They are polygonal squamous cells that have a very thin membrane.
They are modifications of simple columnar epithelial tissue.
Yes, epithelial tissues typically exhibit polarity, with distinct apical and basal surfaces. The apical surface faces the external environment or a body cavity, while the basal surface is anchored to a basement membrane. This polarity allows for the specialized functions of epithelial cells, such as secretion and absorption.

Saquamous cells are flat cells. Single cell layer of these squamous cells is called saqumous cell epithelium. The stratified epithelium means formed of layers [strata] of cells which may or may not be squamous cells. The functions of these layers are different.
New surface epithelial cells are derived from stem cells located in the basal layer of the epithelium. Epithelial cells lining the intestines are derived from stem cells located in the intestinal crypts.
Connective tissue is not lined with epithelial cells.

primary tissue types that exhibit cellularity
Squamous epithelial cells are scale like layers of cells that pose no risk. When referencing rare squamous epithelial cells it just means that there are not a lot of them.
In adults, new surface epithelial cells and the epithelial cells lining the intestine are derived from stem cells located in the basal region of the epithelium. These stem cells continuously divide and differentiate to replace damaged or lost cells, maintaining the integrity and function of the tissue.
Ciliated epithelial cells are found in your pancreas, liver, lung and sinuses.
