Simple Squamous Epithelium Composed of a single layer of flattened cells lying on a basement membrane. In section only their flattened nuclei are often visible. Function: Provides a selective barrier which allows for filtration, passive diffusion and pinocytosis.

A single layer of cuboidal cells with rounded nuclei, lying on a basement membrane. They are often found lining ducts and may possess basal infoldings. Function: They transport fluids and may modify the contents of the lumen by selective absorption.

Function: Absorption, lubrication or movement of luminal contents.
