Respiratory epithelium contains four types of cells:

This epithelium is important for secretion and absorption.

The wall of the collecting tube is made of simple and prismatic epithelium.

The wall of the collecting tube is made of simple and prismatic epithelium.

Simple cuboidal epithelium is adapted for secretion and absorption.

Stratified epithelium differs from simple epithelium in that it is multilayered.

Simple epithelium is a single layer of cells with every cell in direct contact with the basement membrane that separates it from the underlying connective tissue.

The multicellular exocrine glands known as serous glands develop from simple epithelium to form a secretory surface that secretes directly into an inner cavity.
