Simple epithelium is a simple layered sheet of cells that covers the body surface or lines the body cavity
Types:
1. Squamous epithelium: It is made of flattened cells with irregular boundaries. It is found in glomeruli, air sacs of lungs, lining of heart, blood vessels.
2. Cuboidal epithelium: It is made of cube like cells. It is found in kidney tubules, ducts and glands. It is important for secretion and absorption.
3. Columnar epithelium : It is made of column like cells. It lines the digestive tract. It is important for secretion and absorption.
4. Ciliated epithelium : It has cilia at the free end. It is found in bronchi, uterine tubes. It is helpful in propelling materials.
5. Glandular epithelium : Cuboidal or columnar epithelium specialized for secretion is called glandular epithelium. E.g., goblet cells and salivary gland.
