Solution
1. Secretion: Cuboidal epithelium in kidney tubules, ducts.
2. Absorption: Columnar epithelium found in the digestive tract.
3. Filtration: Squamous epithelium found in the glomerulus of the kidney.
4. Ciliated epithelium: Found in the bronchi, uterine tubes propels the materials due to ciliary actions.
