Verified step by step guidance

Understand the function of alveoli: Alveoli are tiny air sacs in the lungs where gas exchange occurs. They need to be thin to allow efficient diffusion of oxygen and carbon dioxide.

Identify the characteristics of epithelial tissues: Different types of epithelial tissues have distinct structures and functions. Simple squamous epithelium is known for being thin and flat, which facilitates diffusion.

Consider the location and function: The walls of the alveoli require a type of epithelium that allows for rapid gas exchange. Simple squamous epithelium is ideal for this purpose due to its thinness.

Compare with other epithelial types: Stratified squamous epithelium is thicker and provides protection, not suitable for gas exchange. Simple cuboidal epithelium is cube-shaped and involved in secretion and absorption, not optimal for diffusion. Transitional epithelium is specialized for stretching, found in the urinary system.

Conclude the reasoning: Based on the need for efficient gas exchange in the alveoli, simple squamous epithelium is the most appropriate type of epithelial tissue for forming the walls of the alveoli.
