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).
No, it is not skin, but a membrane that is found lining all parts of the body that are internal but with an outside exit. These include your entire digestive tract, upper respiratory tract, and urinary/reproductive tracts. This membrane produces mucous and you make plenty of it when you have a upper respiratory infection like a cold.
In the lining of the respiratory tract.
The tissue lining your inner nasal passages is made from ectoderm. However, the rest of the respiratory tract lining is made of endoderm.
Cats
The nasopharyngeal lymphatic tissue is the mucosal lymphoid tissue of the respiratory tract.
The medical term for thin hairs attached to the mucous membrane lining the respiratory tract is "cilia." Cilia help to move mucus and foreign particles out of the airways to keep the respiratory system healthy and functioning properly.
Simple columnar epithelial
Pseudostratified Columnar (ciliated) epithelium lines much of the respiratory tract, but other epithelial tissues are found in the tract as well (for example, simple squamous epithelium in the alveoli of the lungs).
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.
by the spikes made of protein which are inserted into the lipid membrane of the cell.
conducting zones are the upper respiratory tract which is the passage of air and functions to humidify, flter and warm the air. by:- cabdulaahi niyo
