Epithelial cells create the covering layer for your body surfaces. They cover organs and body cavities. In addition, they are in glands. Epithelial cells have many roles in an organism, such as playing a part in secretion, absorption, sensation, protection and transport.

What is the purpose of epithelial cells?

They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception.

What do epithelial cells absorb?

They are simple columnar epithelial cells and play important roles in nutrient absorption (e.g., ions, water, sugar, peptides, and lipids) and in secreting immunoglobulins.
