Epithelial Tissue

Epithelial tissue is a group of cells that form the surfaces covering your body and lining internal organs and cavities. It acts as a protective barrier against injury, infection, and dehydration, while also playing roles in absorption, secretion, and sensation. These cells are tightly packed together, often forming continuous sheets, and are classified based on their shape (such as flat, square, or columnar) and arrangement (single or multiple layers). Epithelial tissue is essential for maintaining your body's integrity and facilitating essential functions like nutrient intake and waste removal.
