Simple columnar epithelial
Cats
The tissue lining your inner nasal passages is made from ectoderm. However, the rest of the respiratory tract lining is made of endoderm.
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.
Any body area that has an outlet to the out side is covered in a mucous membrane: respiratory tact. digestive tract, urinary tract, even the membrane that surrounds the orbit of the eye (eye ball).
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 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 epithelial tissue in the respiratory tract is called respiratory epithelium.
The nasopharynx is lined with ciliated pseudostratified columnar epithelium. This type of tissue helps to trap and remove debris, such as dust and pathogens, from the respiratory tract.
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.
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 nasopharyngeal lymphatic tissue is the mucosal lymphoid tissue of the respiratory tract.
