C
Alveoli of the lungs
D
Lining of the stomach
Verified step by step guidance
1
Understand the characteristics of simple squamous epithelium: It is a single layer of flat cells that allows for easy diffusion and filtration due to its thinness.
Identify the function of the alveoli in the lungs: Alveoli are tiny air sacs where gas exchange occurs, requiring a thin barrier for efficient diffusion of oxygen and carbon dioxide.
Compare the structures listed: The inner lining of the esophagus, surface of the skin, and lining of the stomach are not primarily involved in diffusion processes and have different epithelial types.
Recognize that the alveoli's function aligns with the properties of simple squamous epithelium, making it the correct structure lined with this type of epithelium.
Conclude that the alveoli of the lungs are lined with simple squamous epithelium, facilitating their role in gas exchange.
