The tissue that lines internal organs is called epithelial tissue. It acts as a protective barrier and helps with the absorption and secretion of substances in the body. Epithelial tissue can be found in the digestive tract, respiratory tract, and other organs.
The epithelial tissue in the respiratory tract is called respiratory epithelium.
Epithelial tissue lines body surfaces such as the skin, respiratory tract, and digestive tract. It acts as a protective barrier against pathogens, regulates the exchange of substances between the body and external environment, and helps to maintain homeostasis.
In the lining of the respiratory tract.
The type of epithelial tissue that lines the urinary tract are a special form of epithelium cells. These cells allow the tract to stretch.
The type of epithelial tissue that lines much of the respiratory tract is called pseudostratified columnar. This type of tissue also moves substances across its surface.
epithelial tissue.
Epithelial tissue can be found covering the surfaces of organs in the body, such as the skin, lining the digestive tract, respiratory tract, and blood vessels. It also lines body cavities and forms the outer layer of the skin.
Pseudostratified ciliated columnar epithelium. This lines the nasal cavity as well as the trachea. The oral cavity, as well as the pharynx, is lined with stratified squamous epithelium, due to obstructions from food.
