3. Role of Vitamin A in Epithelium Vitamin A maintains the normal structure and function of epithelial cells. It helps in mucus production.It prevents keratinization, keeping the tissue soft and flexible

4. Changes in Chronic Vitamin A Deficiency Epithelial cells change from columnar to keratinized squamous type. Mucus secretion decreases, leading to dryness. Keratinization occurs, making the surfaces rough and dry. Barrier function weakens, increasing infections.Affected organs: eyes, skin, respiratory system
