Detailed explanation-1: -The covering or protective tissues in the animal body are epithelial tissues. Epithelium covers most organs and cavities within the body. It also forms a barrier to keep different body systems separate.

Detailed explanation-2: -Protection: Epithelial tissue protects several aspects of your body. For example, your skin is made up of epithelial tissue and protects the tissues deeper in your body, such as blood vessels, muscle and internal organs.

Detailed explanation-3: -What Is Epithelial Tissue? Epithelial tissue or epithelium forms the outer covering of the skin and also lines the body cavity. It forms the lining of respiratory, digestive, reproductive and excretory tracts. They perform various functions such as absorption, protection, sensation and secretion.

Detailed explanation-4: -Epithelium or epithelial tissue is one of the four basic types of animal tissue, along with connective tissue, muscle tissue and nervous tissue. It is a thin, continuous, protective layer of compactly packed cells with a little intercellular matrix.

Detailed explanation-5: -Based on the cell shape, epithelial tissue is classified into squamous, cuboidal or columnar. Depending on the number of layers, the tissue is divided into simple or stratified. Subclassifications include pseudostratified, ciliated or transitional. Glandular epithelial cells produce and release various macromolecules.
