Detailed explanation-1: -Being able to readily diffuse material through itself, such as occurs in alveoli, is a characteristic of the simple squamous epithelial tissue.

Detailed explanation-2: -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-3: -Squamous epithelial cells in the alveoli allow oxygen from the air to enter the blood in the capillaries of the lung. Carbon dioxide, a waste product, passes across the epithelium of the alveoli to be removed from the body.

Detailed explanation-4: -A simple squamous epithelium is a simple epithelium made up of squamous epithelial cells. The squamous epithelial cells are characterized by being flat, possessing an oblong nucleus, and having a scale-like appearance. The cells are wider than they are tall and appear somewhat hexagonal when viewed from above.

Detailed explanation-5: -Explanation: Alveoli are the site of gas exchange in the lungs. Because rapid diffusion of gases is necessary between the capillaries and the alveoli, a very thin epithelial layer is needed. As a result, alveoli use simple squamous epithelium so that gases can easily diffuses to and from the bloodstream.
