Questions & Step-by-Step Solutions
What type of epithelium lines the alveoli of the lungs?
Step 1: Understand what alveoli are. Alveoli are tiny air sacs in the lungs where gas exchange occurs.
Step 2: Know what epithelium is. Epithelium is a type of tissue that covers surfaces in the body.
Step 3: Identify the type of epithelium in the alveoli. The alveoli are lined with a very thin layer of cells.
Step 4: Recognize that this thin layer is called simple squamous epithelium.
Step 5: Understand why simple squamous epithelium is important. Its thin structure allows oxygen and carbon dioxide to easily pass through, making gas exchange efficient.
