Alkaline mucus : ウィキペディア英語版 | Alkaline mucus Alkaline mucus is a thick fluid produced by animals which confers tissue protection in an acidic environment, such as in the stomach.〔http://link.springer.com/article/10.1007%2FBF01976227 Hwang, S. H., M. Litt, and W. C. Forsman. "Rheological Properties of Mucus." Rheologica Acta 8.4 (1969): 439. Springer Link. Web. 27 July 2014 〕 == Properties of alkaline mucus == Mucus that serves a protective function against acidic environments generally has a high viscosity, though the thickness and viscosity of the mucus layer can vary due to several factors. For example, alkaline mucus in the stomach increases in thickness when the stomach is distended. The pH level of the mucus also plays a role in its viscosity, as higher pH levels tend to alter the thickness of the mucus, making it less viscous.〔http://link.springer.com/article/10.1007%2FBF01976227 Hwang, S. H., M. Litt, and W. C. Forsman. "Rheological Properties of Mucus." ''Rheologica Acta'' 8.4 (1969): 439 〕 Because of this, invading agents such as helicobacter pylori, a bacteria that causes stomach ulcers, can alter the pH of the mucus to make the mucus pliable enough to move through.〔http://web.mit.edu/nnf/publications/GHM133.pdf Celli, J.

Web. 27 July 2014.〕 Exposure to atmospheric air also tends to increase the pH level of alkaline mucus.〔http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-879X2001000600011 Correa, C.H.M., A.L.G.
