Transitional zone - It resembles the histological structure of the rectum but it presents both simple columnar epithelium and stratified squamous epithelium. Esophageal mucous membranes work in conjunction with a muscular portion to The molecules within the lamina propria act as a series of chains and hooks, to lock the cells and membrane into place. The system consists of the nose and the nasal cavities, which in their upper parts support the olfactory mucous membrane for the perception of smell and in their lower parts act as respiratory passages. The mucous membrane of this region contains special nerves designed for smell.

The membranes line the passageways in our bodies that connect to the outside environment. Mucus is a viscous fluid secreted by epithelial cells of mucous membranes that entraps invading microorganism. What is mucus? Some mucous membranes secrete mucus, a thick protective fluid. Pericardium - the serous membrane that surrounds the heart. It is often adapted for secreation and absorbtion. Mucous membranes are moist because of the presence of glands which secrete a thick fluid known as mucus, and they are important for a number of bodily functions. Mucous membranes line the urogenital tract, digestive tract, and respiratory tract, with one of the more well known mucous membranes being the lining of the interior of the nose. Pleura - the serous membrane that surrounds the lungs. The entire digestive tract is lined with mucous membranes. The active surface of this membrane, on which the important functions of the nose take place, is greatly expanded by the irregular anatomy of the nasal walls (turbinates, meatuses, septum, etc.) Mucous: Lines all body cavities that open to the exterior body surface. Mucosa (mucus membrane) is an epithelial membrane containing mucosal cells that secret mucus, a gel-like fluid containing mainly water (~95%), mucins (0.5–5%), inorganic salts (~1%), proteins (0.5–1%), lipids, and mucopolysaccharides [23,24]. Pericardium - the serous membrane that surrounds the heart. The nose is covered by a complex mucous membrane.

Secreted mucous traps the pathogens in the body, preventing any further progression of microbes. Most mucous membranes contain stratified squamous or simple columnar epithelial tissue. The epithelial tissue sheet lies directly over the layer of loose connective tissue called lamina propria. The mucus traps bacteria and foreign particles, which keeps them from invading the tissues and aids in their removal from the body. The main function of the mucous membrane and the mucous is to keep the tissue moist (for example in the respiratory tract, including the mouth and nose). The mucous membrane is thickest, and most vascular, over the nasal conchae.
