Detailed explanation-1: -The bronchioles are lined by simple columnar to the cuboidal epithelium, and the alveoli possess a lining of thin squamous epithelium that allows for gas exchange.

Detailed explanation-2: -Different types of epithelial cells based on shape include: Squamous epithelium: Squamous epithelial cells are flat and sheet-like in appearance. Cuboidal epithelium: Cuboidal epithelial cells are cube-like in appearance, meaning they have equal width, height and depth.

Detailed explanation-3: -A simple squamous epithelium, also known as pavement epithelium, and tessellated epithelium is a single layer of flattened, polygonal cells in contact with the basal lamina (one of the two layers of the basement membrane) of the epithelium.
