Epithelial Cells

Epithelial cells are a type of cells that form the lining of surfaces and cavities in the body, such as the skin, mouth, and internal organs. They create a protective barrier, help with absorption (like in the intestines), and assist in secretion (such as sweat or mucus). These cells are tightly packed together, forming continuous sheets that shield underlying tissues from harmful substances, pathogens, and mechanical damage. Epithelial cells are important for maintaining body integrity, facilitating nutrient exchange, and supporting organ functions, playing a vital role in overall health and protection.
