Which type of epithelial tissue is best suited for rapid diffusion in the walls of pulmonary alveoli?
Correct answer: A. Simple squamous epithelium
- A. Simple squamous epithelium
- B. Stratified squamous epithelium
- C. Simple cuboidal epithelium
- D. Transitional epithelium
Explanation
Simple squamous epithelium is only one cell layer thick, so it permits efficient diffusion of oxygen and carbon dioxide in the alveoli. Stratified squamous tissue provides protection, while cuboidal and transitional tissues have different functions.
