Simple squamous epithelium is found in areas like the alveoli of the lungs and blood vessels. Which of the following best explains why this tissue is suited for diffusion?
| 1. | It is composed of multiple layers of cells, providing strength. |
| 2. | It has cilia that move substances across the surface. |
| 3. | It is thin and flat, forming a single layer for efficient exchange. |
| 4. | It secretes mucus to trap particles and prevent damage. |
