A) Epithelial tissue is a type of animal tissue that forms the covering of all body surfaces, lines body cavities and hollow organs, and is the major tissue in glands. It is characterized by closely packed cells with little extracellular matrix, forming continuous sheets. Epithelial tissues are avascular (lack blood vessels) and are anchored to underlying connective tissue by a basement membrane. Their primary functions include protection, secretion, absorption, excretion, and filtration.
