stratified epithelium), which serves as a protective layer against external and internal invaders, and secretory glandular epithelium. According to its main function, epithelial tissue can be categorized into non-secretory surface epithelium (e.g. The epithelium covers most of the outer and inner surfaces of the body, including the skin, urogenital system, and the digestive and respiratory tracts. Epithelial tissues are composed of one or multiple layers of epithelial cells separated from the underlying connective tissue by the basement membrane, a thin sheet of collagen that provide structure to the epithelium. There are a variety of glands releasing substances that perform important roles in the human body.The epithelial tissue is one of the four major tissues found in the human body, along with connective tissue, muscular tissue, and nervous tissue. Glandular epithelium is arranged into structures known as glands, which can either be a single cell or a group of cells specialized in producing and releasing a specific substance. Glandular epithelium, also known as glandular tissue, refers to a type of epithelial tissue involved in the production and release of different secretory products, such as sweat, saliva, breast milk, digestive enzymes, and hormones, among many other substances.
