2. separate two cells from each other
3. stop substance from leaking across a tissue
4. performing cementing to keep neighbouring cells together

Choose the correctly matched pair:

1. Inner surface of bronchioles - squamous epithelium
2. Moist surface of buccal cavity - Glandular epithelium
3. Inner lining of salivary ducts - Ciliated epithelium
4. Tubular parts of nephrons - Cuboidal epithelium
