Verified step by step guidance

Understand that epithelial tissues are specialized tissues that cover surfaces, line cavities, and form glands. Their classification is based on structural characteristics that relate to their function.

Learn the two primary parameters used to classify epithelial tissues: (1) the shape of the cells and (2) the number of cell layers present.

Explore the three main cell shapes: squamous (flat and thin), cuboidal (cube-shaped), and columnar (tall and column-like). These shapes are key to understanding the classification.

Examine the number of cell layers: (1) simple epithelium (a single layer of cells) and (2) stratified epithelium (multiple layers of cells). This distinction helps determine the tissue's role in protection or absorption.

Recognize that the correct answer is 'Cell shape and number of cell layers,' as these parameters are universally used to classify epithelial tissues in Anatomy & Physiology.
